DJ King Flow interviews Coast LoCastro for Mixtape Addict 91.

French DJ and producer DJ King Flow returns with a new edition of Mixtape Addict, delivering a carefully curated exploration of underground hip hop. Broadcast via Scientific Sound Asia, the Vietnam-based international radio station and promoter, the programme continues to operate as a global platform for artists committed to the core values of hip hop culture.

DJ King Flow began his journey at the age of fourteen, shaping a style rooted in boom bap while maintaining a contemporary perspective. His sound draws from the foundations of 90s hip hop while remaining connected to the present, consistently supporting emerging voices across the underground scene.

This ability to bridge generations has earned him recognition from listeners and artists worldwide, establishing him as a trusted selector within lyrical hip hop. Over the years, he has collaborated with influential figures including Ras Kass, Tragedy Khadafi, O.C., Juicy J and Khujo Goodie, relationships that reflect his continued commitment to preserving the genre’s lineage.

Since launching Mixtape Addict in 2015, DJ King Flow has developed the series into a respected hub for independent artists, combining radio broadcasts, interviews and mixtape releases to highlight genuine talent and reinforce the strength of the underground community. Alongside his work as a selector, he continues to expand his creative output as a producer.

His instrumental album The Adventures of F.J. Parker brings together jazz-influenced melodies, soulful textures, deep grooves and the gritty character associated with classic hip hop production. In recent years, he has expanded his catalogue with projects such as Trill Legacy (Instrumentals), a beat-focused release built around layered production and cohesive sonic themes, alongside tracks including Warzone featuring Ice Crimi and Win or Lose featuring Imam T.H.U.G.

His collaboration Money with Lex Lakaiser reinforced his presence within contemporary underground hip hop, while mixtape compilations such as Industry Pirates 2, Industry Pirates 3 and Time Travel (Beat Tape) reflect continued creative activity. His 2025 releases, including Money, Give the Town Some Hope and additional forthcoming collaborations, demonstrate ongoing artistic development and a clear dedication to the craft.

Interview Guest: Coast LoCastro.

Coast LoCastro is an underground hip hop artist associated with the East Coast scene, recognised for gritty lyricism, direct delivery and a strong connection to boom bap traditions. His work reflects a street-focused perspective, built around stripped-back, sample-driven production that places emphasis on clarity, rhythm and lyrical control.

He has developed his profile through consistent collaboration, most notably alongside producer Johnny Slash. Their joint releases, including tracks such as Showin Ass, Wannabe Frenz featuring Lil Vic, and Meanwhile In Gotham featuring Apathy and Lil Dee, highlight a cohesive partnership built on hard drums, cinematic sampling and focused writing. These records have helped establish his presence within curated underground DJ sets and independent platforms.

His catalogue continues to grow through collaborative projects and independent releases, reinforcing his role within the current boom bap landscape. His music frequently appears within mixtape culture, where strong bars and cohesive production remain essential, aligning naturally with DJ-led formats such as Mixtape Addict.

Lyrically, Coast LoCastro focuses on themes of loyalty, identity and street experience, delivered through a controlled and confident flow. His writing avoids unnecessary complexity, instead prioritising direct expression and consistency, qualities that connect with listeners who value traditional hip hop structure and authenticity.

Within the wider underground network, he operates alongside a circle of independent artists and producers who maintain a similar approach to hip hop, favouring substance over trend-driven output. This positioning reinforces his credibility within the East Coast-inspired boom bap revival, where emphasis remains on lyrical discipline and production integrity.

Within the context of Mixtape Addict, Coast LoCastro represents a contemporary underground voice grounded in classic hip hop values, contributing to the show’s focus on authenticity, sharp lyricism and cohesive sound selection.

The session opens with Coast LoCastro and Johnny Slash setting a raw underground tone through Showin Ass, Wannabe Frenz and Meanwhile In Gotham, combining gritty Boom Bap drums with sharp East Coast lyricism. Three In The Chamber intensifies the cypher energy, while C Ki C Tip keeps the momentum grounded in stripped-back underground production.

The mood deepens through Brownsville OG and Legendary, reinforcing street authenticity before the tension rises with Agent Provocateur and The Algorithm, both delivering direct battle energy. American Hustler brings a more polished street perspective while maintaining the episode’s hardcore edge.

The middle section returns to lyrical focus with Steel Sharpens Steel and The Brothers Grimm, pushing classic Boom Bap intensity. Finesse injects energy through Araabmuzik’s production, while Remember introduces a reflective moment before Body Blows restores aggressive punchline delivery.

The closing stretch moves through darker tones with Donner Pass before Trip Barrel rounds out the underground feel. DJ King Flow concludes with an in-depth interview with Coast LoCastro, framing Episode 91 as a cohesive Boom Bap session rooted in battle culture, street realism and underground collaboration.

The live broadcast is scheduled for Tuesday, March 24th, 2026, from 8 to 10 PM Indochina Time (ICT), with a repeat airing on Saturday from 8 to 10 AM (ICT).
