The station operates as an underground electronic music radio platform, DJ agency and promoter serving expatriate and local audiences across India, Japan, Sri Lanka, Cambodia, the Philippines and the wider Asian region.

Based in Bogotá, Colombia, The Lab Sessions (TLS) is an artistic electronic music collective that has been steadily building a strong presence through curated showcases and large-scale events. Their mission is to present an authentic representation of Colombia’s underground electronic music scene, with a clear focus on supporting and elevating Colombian DJs.

Alongside international influences, TLS delivers high-quality artistic programming to a diverse audience made up of both locals and listeners from multiple nationalities. This approach highlights the depth of talent within Colombia, demonstrating that forward-thinking underground music is not only imported but actively created and performed by local artists with significant potential.

Since 2016, TLS has organised events across South America, performing at a wide range of respected venues and clubs. These include Octava, Klan 31, Teatron, KAPUTT, Vagabond, Bud-X Colombia, Top Secret Medellín, Armando Records, Céntrico, Mambo Alive, Sutton, Montibus Fest, Bassline events, TLS Parties, Euro Techno, Madame Garden and La Fabryka in Cali, Victoria, Masha, Vlak and Lede Club, with more recent appearances at Groove and Dirty Sanchez in Quito, Ecuador.

Guest DJ Takamasa Owaki (first hour).

This week’s first guest DJ is Takamasa Owaki, hailing from Kamo-gun in Japan. His career began internationally, with early appearances across South America, including events in Colombia, Brazil and Ecuador, experiences that helped shape his open-minded and genre-fluid approach to DJing.

Rooted in House, Nu Disco and Tech House, Takamasa’s sound reflects nearly two decades of musical influence. Alongside electronic music, his background draws heavily from 1980s and 1990s culture, Disco and Rock, with classical music also playing a formative role from an early age through his father’s influence.

At the age of 23, he spent two years in the United States as an agriculture trainee, immersing himself in a wide range of styles including electronic music, hip hop, reggae and Latin sounds. This period proved pivotal, solidifying his direction as a DJ. After returning to Japan, he balanced his work as a florist with regular DJ appearances in cafés and bars, steadily refining his craft.

Operating under his Cactus Experience concept, Takamasa Owaki delivers tracks that move fluidly between Disco, Afro House, Psychedelic textures and Ambient passages, while maintaining a strong focus on Deep House and Soulful House. His selections favour urban, refined atmospheres and hypnotic grooves, designed to unfold gradually and with emotional intent.

A vinyl-trained DJ, Takamasa has held residencies at a number of international venues, including Lavista Nightclub at the InterContinental Hotel Doha, The Warehouse Wine & Tapas at Pearl Rotana Abu Dhabi, Impressions Lounge at Anantara Abu Dhabi, ToroToro at Etihad Towers and Hard Rock Café Bogotá. Today, his Cactus Experience sessions continue to evolve, offering immersive journeys that move deeper into mood, rhythm and subconscious flow.

Guest DJ Andres Fierro (second hour).

This week’s second guest DJ is Andrés Fierro, born and raised in Colombia and active in the electronic music scene since the late 1990s. Beginning his career in 1997, he quickly developed a personal and recognisable approach that set him apart, earning him long-standing respect as both a DJ and producer within the country’s underground circuit.

His sound resists strict categorisation, moving fluidly between Progressive House, Tech House and Techno with a natural sense of balance. Fierro’s sets are driven by solid low-end pressure, rhythmic intensity and controlled energy, allowing him to shift moods and tempos without disrupting the flow of the dancefloor. This versatility has become a defining feature of his performances.

Over the years, he has become a resident DJ at some of Colombia’s most respected underground venues, including Cinema, where he continues to perform regularly. Beyond his residencies, Andrés Fierro has appeared at clubs and festivals across the country, steadily reinforcing his position within the scene.

His career has also seen him share line-ups with internationally recognised artists such as César del Río, José de Melero, El Pasha, El Divino, John Acquaviva, Carl Cox, Felipe Volumen, Nick Warren, XL Garcia, Santos and Darren Emerson. With decades of experience behind the decks, Andrés Fierro remains a consistent and influential presence, delivering focused, high-energy sets rooted firmly in underground club culture.

The first hour, mixed by Takamasa Owaki, focuses on House-rooted selections with a strong soulful and disco influence. Tracks such as Speak To Me and Soul Shoes establish a classic House foundation, while Side Walk Hustle and Time introduce Disco House and Soulful House structures shaped by vocal arrangements.

As the set progresses, deeper tones emerge through Lost Islands and Emptiness, supported by the Jazzy House textures of The Sluggard. Heaven brings a Vocal House element, while For The Love Of You in Conway’s Afro-Conna Funk edit adds a Soulful House reinterpretation of a classic source.

The latter part of the hour introduces stylistic contrast with 747-s bridging Breaks and House, followed by Intro Nature moving into Organic House. For Days closes the first session with a Nu Disco approach, shifting away from traditional House forms while maintaining continuity.

The second hour, curated by Andres Fierro, centres on Tech House and Minimal Deep Tech. Tracks such as Cha Cha Slide, Pleasure Beat and Beat Won’t Stop form a consistent Tech House run, while Palo, Keep The Temper and Bouquet bring a stripped-back Minimal focus. The episode concludes with stylistic variety through Baby in the Leandro Da Silva remix and Feather Light, closing the session with Funky House and Electronica influences.
