Dust off your UFOs, visors, and pacifiers: just in time for Halloween, old-school rave-promotion team Stuck on Earth returns from the blissed-out, all-nighter dead for Baby BOO at the newly re-opened Studio B. The annual BOO events were a NYC dance-party mainstay in the late '90s and early 2000s, bringing DJs and turntablists of all genre persuasions to venues like Randall's Island. Tonight's headliner is iconic hip-hopper Grandmaster Flash, who's backed up by drum 'n bass madmen J Majik and Danny the Wildchild, dependable locals Christian Bruna and Empress, and many others.
