Denver is often touted as the bass-music capital of the world, thanks to the city's longstanding underground dance-music scene, raging warehouse parties and sweaty, head-banging fans. While some of that underground energy has floated into massive venues run by mainstream promoters, the spirit of the rave scene pulses on at the Black Box, a club owned and run by longtime Sub.mission promoter Nicole Cacciavillano, who set up the space to make sure Colorado's scene would have a welcoming home with a killer Basscouch Sound combo and a community vibe. While the venue itself just opened in 2016, its roots run deep...bass deep.
