Massacooramaan (Dave Quam) delivers slappers from all corners of the rap multiverse (and the global dance scene) to an eager Black Book dance floor most Friday nights at the Cave. You'll hear Young Thug and a hot Rihanna remix, don't worry—but Massacooramaan pulls from his deep knowledge of international club bangers to keep dancers surprised, weaving through the latest mixtape fire, throwback dancehall, and crossover reggaeton without dropping the beat. Arrive early—Black Book's tiny space and the Cave's reputation for turn-up mean those looking for refuge from the Top 40 noise of the Old Town strip will be showing up, so expect a line after 11 pm.
