French DJ and producer DJ King Flow returns with another edition of Mixtape Addict, this time featuring Heartbreak JC on Scientific Sound Asia. Scientific Sound Asia operates as an international radio station, promoter, DJ agency and music news platform supporting artists connected with both the foundations and continuing development of Hip Hop culture.
DJ King Flow began DJing at the age of fourteen and developed a style firmly rooted in Boom Bap. The influence of 1990s Hip Hop remains central to his approach, although his selections consistently place newer underground artists alongside established names rather than treating the music purely as nostalgia.
That connection between generations has become an important part of his identity as both a selector and producer. Hard drums, sample-driven production and lyric-focused records sit alongside contemporary independent releases from artists continuing those traditions across different parts of the world.
His career has included collaborations with established names including Ras Kass, Tragedy Khadafi, O.C., Juicy J and Khujo Goodie. These projects reflect a long-term commitment to the foundations of the culture while keeping his production work connected with artists active across the present underground scene.
In 2015, DJ King Flow launched Mixtape Addict as a platform dedicated to independent Hip Hop. What began around mixtapes and radio developed into a wider project combining regular broadcasts, artist interviews, new music and direct support for rappers, DJs and producers.
The interview side of Mixtape Addict has become an important part of the project because it gives artists more space to discuss their careers, influences and current work. These conversations sit alongside the music and provide listeners with additional context around the people, labels and independent networks behind many of the records featured on the programme.
DJ King Flow’s wider activity can be followed through Facebook, X and the Mixtape Addict YouTube channel. These platforms extend the project beyond radio through interviews, videos, releases and other material connected with the international underground.
Production has also become an increasingly visible part of his work. His instrumental album The Adventures of F.J. Parker combines Jazz-influenced melodies, soulful textures and deep grooves with the raw drum-led character associated with classic beatmaking.
Trill Legacy (Instrumentals) developed that side of his catalogue further by placing the emphasis entirely on his production. Without an MC at the centre, the project gives the arrangements, samples, drums and melodic ideas more room to demonstrate how his style operates independently.
His collaborative releases continue to connect that production work with underground rappers from different scenes. Warzone featuring Ice Crimi, Win or Lose featuring Imam T.H.U.G. and Money with Lex Lakaiser show how his beats can support contrasting vocal approaches while retaining a recognisable identity.
More recent work includes Back To Basics (Mixtape Addict) featuring Faf Larage, Napoleon Da Legend, Relo and DJ Djel. The project brings several voices together around the musical principles that have remained central to DJ King Flow’s work since his earliest years behind the decks.
Bills (Remix) featuring Khujo Goodie extended his connection with established American artists, while Laser Rouge with Omaz and Joe Mack returned to the collaborative underground format that runs throughout his catalogue. The Movement featuring ISH-ONE added another international connection and reinforced the global outlook behind Mixtape Addict.
That international direction also appears through Legacy with Dnzl Izm and Northwest Flow with Seattle emcee King Khazm. Rather than concentrating exclusively on French or American artists, DJ King Flow uses Mixtape Addict to connect independent voices from different locations through a shared respect for lyricism, beatmaking and underground culture.
This edition continues that approach with Heartbreak JC joining the programme as the featured artist. His appearance fits naturally within Mixtape Addict’s focus on lyric-driven underground Hip Hop and artists carrying traditional MC culture into the present.
Interview Guest: Heartbreak JC.
Heartbreak JC is a Memphis, Tennessee rapper and songwriter, born in 1997, whose work combines Southern rap roots with darker, atmospheric production and a strong emphasis on personal experience. He has cited 2Pac, The Notorious B.I.G., Kingpin Skinny Pimp and Yo Gotti among the artists and records that shaped his musical outlook, while his own catalogue has developed around direct storytelling and a distinctly Memphis perspective.
His early musical background began in church, where he first learned piano before moving on to guitar. That foundation eventually developed into rap, with Heartbreak JC later describing Voices as the first record that significantly expanded his audience and helped take his music beyond his home city.
A major recent phase of his career has come through his work with DJ Muggs, the veteran producer associated with Cypress Hill and Soul Assassins. Their collaborations have given Heartbreak JC a darker and more cinematic production setting, pairing his Memphis delivery with heavy drums, sparse arrangements and the sample-led approach closely associated with Muggs’ catalogue.
That partnership produced a steady run of releases across 2025 and 2026. Blood On The Floor arrived in 2025, followed by material including Soul Flight To Paradise, LUV, Pay Attention and the Lay It Down album through Soul Assassins Records.
The Lay It Down project continued that collaboration with tracks such as Slide, LUV and the title track. Across these recordings, Heartbreak JC’s writing remains front and centre, while DJ Muggs provides a restrained production style that gives the vocals room to carry the atmosphere and narrative.
Heartbreak JC’s wider catalogue also includes releases such as Stay Dangerous, Jesus Piece, Red Lights & Drive Thrus and the 2026 album 5th Ave. These projects show a productive period in his career, with frequent releases and a growing connection to the Soul Assassins camp.
His background remains closely tied to Memphis, both musically and personally. Heartbreak JC has spoken about performing on Beale Street as one of the memorable moments of his career, while performances in Los Angeles and ambitions to eventually play Times Square reflect the broader direction of his current work.
Overall, Heartbreak JC brings together Memphis rap tradition, personal storytelling and a contemporary underground production aesthetic. His recent work with DJ Muggs has become one of the clearest expressions of that identity, linking Southern rap influences with the darker production lineage of Soul Assassins.
DJ King Flow opens Mixtape Addict Show Episode 115 with three tracks from Heartbreak JC and DJ Muggs, immediately establishing a darker underground tone built around dusty drums, cinematic sampling and hard-edged lyricism. Soul Flight To Paradise, Lay It Down and Jesus Piece place Heartbreak JC at the centre of an opening run closely aligned with Boom Bap and the grimier side of Underground Hip Hop.
JR Writer, Hell Rell and Vado then bring a clear Harlem and Dipset-rooted character through Started From Nothing, before DJ King Flow's remix of Crimeapple adds another stripped-back East Coast selection. Obleak with Ruste Juxx and Yotto Beatz and Nutso continue the East Coast Hip Hop direction with rugged drums, street-focused writing and a strong New York underground feel.
Mitchy Slick and Ise-B shift the geography towards San Diego with First Rounders, while Derange Da Messiah provides another independent lyrical cut before P-Lo, Clyde Carson, Iamsu! and Ezale make the Bay Area influence unmistakable on Bay Boyz 4ever. That section introduces a stronger West Coast Hip Hop presence, contrasting the colder East Coast production of the opening half with a looser regional bounce.
Talib Kweli and Planet Asia maintain the lyrical emphasis with Repentance, linking Brooklyn-conscious rap with Fresno-rooted West Coast lyricism. Napoleon Da Legend, Dub Sonata and Tone Spliff follow with Sports Vet (Overtime), before Atlanta's 4-IZE adds a Southern strand through Ya Blind, broadening the regional spread without losing the episode's focus on independent emceeing.
DJ King Flow returns to JR Writer and Hell Rell with his remix of I Will Not Lose before 38 Spesh and Curtis Coke add another upstate New York street-rap selection through Great Wall. Imam THUG and Young Amsterdam then close the music section over DJ King Flow production, giving the final stretch a direct connection to the show's host before the episode finishes with an interview with Heartbreak JC.
Across Episode 115, New York Boom Bap and East Coast street rap form the main backbone, while San Diego, the Bay Area, Fresno and Atlanta introduce clear regional contrasts. The episode remains centred on underground lyricism, hardcore rap, mafioso-influenced street writing and sample-driven production rather than broad mainstream Hip Hop.
DJ King Flow welcomed Memphis MC Heartbreak JC to Mixtape Addict for a conversation about DJ Muggs, Memphis Hip Hop, artistic identity, mixtape culture and the work behind his forthcoming material. Heartbreak JC spoke openly about the people who helped him develop, the importance of remaining teachable and how years of work are now opening new opportunities for his music.
Asked to name his favourite DJ, Heartbreak JC immediately chose DJ Muggs, crediting him with having a major influence on Hip Hop far beyond the West Coast. What JC admires most is Muggs' refusal to abandon his own sound as trends changed, seeing that consistency as an example of how an artist can develop without chasing whatever happens to be popular at the time.
Their connection developed indirectly through Memphis veteran Skinny Pimp, who supported JC early and helped teach him about music and the business surrounding it. Producer Cordell later took Memphis vocals back to Los Angeles, where Muggs heard JC's distinctive voice, contacted him and began a working relationship that has grown steadily since.
Heartbreak JC used that story to emphasise the importance of putting yourself in situations where opportunities can develop naturally. Whether performing for thousands of people or only a small crowd, he believes every room matters because a single person present could eventually create an unexpected connection.
JC confirmed that he and DJ Muggs are working on a new album, although the project is still being shaped and no release date has been fixed. He described an intense recording schedule and said Muggs has been taking the Memphis characteristics in his voice into production territory JC would never previously have chosen for himself.
Rather than simply placing JC over familiar Southern production, Muggs has introduced darker and harder beats that have forced him to explore a different side of his delivery. JC believes this combination gives the forthcoming material its own identity, connecting his Memphis roots with production that reaches into a different branch of underground Hip Hop.
Heartbreak JC said maintaining his own identity requires deliberately blocking out much of the noise surrounding trends, social media and the constant pressure to manufacture a hit. He listens to everything from Rock and Gospel to Soul and Pop, but refuses to compromise his principles simply to gain attention or fit into a current commercial formula.
That independence carries directly into his writing because he wants the records to come from his actual experiences rather than from a character created for promotion. JC argued that working on himself, his health, his focus and his discipline ultimately strengthens the music more than spending all his energy watching what other artists are doing.
Asked what younger MCs should learn from his experience, Heartbreak JC placed listening at the top of the list. He said artists need to accept constructive criticism and remain willing to learn from people with more experience, recalling recent time around figures such as DJ Muggs and Ice-T as opportunities to absorb knowledge rather than prove how much he already knows.
His advice was to write useful information down, remember it and recognise that a lesson may only become relevant months or years after it is first given. JC sees the inability to listen as one of the biggest obstacles facing developing artists because somebody convinced they already know everything leaves little room for genuine improvement.
JC's musical foundation began much earlier in church, where he played piano and watched his grandfather work with the sound system. That early exposure to instruments and audio equipment gradually developed into recording and beat-making, although he freely admitted that it took years of experimentation before he became confident in what he was creating.
The point at which music became more than an interest came when he realised he felt incomplete if he was not making beats, writing or performing. Now approaching 29, JC said the larger opportunities are only beginning to arrive despite having worked on music since his mid-teens, reinforcing his belief that artists cannot predict when persistence will finally create an opening.
That experience also shaped the way he treats supporters, DJs and people he meets along the way. Heartbreak JC stressed that nobody should be treated as insignificant, because the child playing a record in the neighbourhood or the person standing in a crowd of 25 may eventually become one of an artist's strongest supporters or create an opportunity nobody could have anticipated.
The traditional mixtape era remains another major influence, with JC remembering how artists such as Lil Wayne could release several tapes between albums and sometimes produce material that connected even more strongly than the official record. He feels the decline of that culture removed an important outlet for freestyles, experimentation and rappers proving themselves over existing beats without every release needing to function as a formal album.
When asked what he wants from a mixtape, JC described something closer to a complete story than a collection of disconnected records. He wants grime, emotion, hardship, success, strong concepts and the ordinary experiences between the major events, arguing that artists should explain what happened before the money or recognition rather than presenting only the final result.
Bars remain essential, but Heartbreak JC believes substance and creative concepts are what give a project depth. His ideal release should be able to shift between different emotions and situations across its running time, leaving the listener feeling that they have experienced several sides of the artist rather than hearing the same subject repeatedly.
Looking further ahead, JC said listeners should expect singles, videos and a substantial amount of unreleased material before the new album finally arrives. He and Muggs have deliberately avoided announcing a date because songs are still being replaced whenever stronger material is recorded, with the aim of making the finished project as strong as possible rather than rushing it out.
Heartbreak JC closed by thanking King Flow, the listeners in France and supporters elsewhere who have followed his work as his profile has grown. He encouraged people to keep their priorities in order, remain focused and stay connected to the new music, while also expressing interest in eventually bringing his live show overseas.
The live broadcast is scheduled for Tuesday, September 22nd, 2026, from 8 to 9 PM Indochina Time (ICT), with a replay set for Saturday from 8 to 9 AM (ICT).
