The concrete walls of Eastpark Underpass will once again become the setting for Obsidian, as the underground techno concept returns to Phoenix on November 6 and 7. Produced by Relentless Beats and Body Language in partnership with Techno Snobs, the two-night event will bring a hard-charged lineup and industrial atmosphere beneath the city.
Built around the darker side of techno, Obsidian transforms the underpass into a setting that matches its sound. Concrete, graffiti art, and the hum of the surrounding city provide the backdrop for two nights centered on raw, driving rhythms and the uncompromising energy of the underground.
The lineup brings together an international collection of techno artists, with Adrian Mills, Baugruppe90, Boys Noize, Chris Liebing, DJ Stingray 313, Frederic., ØTTA, SoFFT, The Chronics, and Truncate set to take over the underpass. Anthony Ray and Audrey Voss will also provide support across the event.
Rather than separating the music from its surroundings, Obsidian is designed around the relationship between the two. The industrial setting of Eastpark Underpass gives the event a natural edge, creating an environment where pounding rhythms and immersive production can play off the concrete surroundings and graffiti-covered walls.
The return also continues the growing relationship between Relentless Beats, Body Language, and Techno Snobs, bringing their shared focus on underground techno to a unique Phoenix location. For fans looking for a darker alternative to traditional festival environments, Obsidian offers two nights built around club-driven sounds and a distinctly underground atmosphere.

Tickets for Obsidian are on sale now, starting at $100+, through the official event website. The event is open to attendees 18 and over. Fans can also follow Obsidian on Instagram for the latest announcements, updates, and event information.
With two nights of hard techno, immersive production, and an unmistakably industrial setting, Obsidian is once again inviting the Phoenix techno community to leave the surface behind and descend beneath the city. Visit Relentless Beats for information on all Relentless Beats events.
