Thu 21 Deluxe presents DJ Marky & XRS Sullivan Room 218 Sullivan St between Bleecker and W 3rd Sts (212-252-2151). Subway: A, C, E, B, D, F, V to W 4th St. 10pm; $TBA, $12 before midnight.

The Bass:Mint gang, in cahoots with the Agency, aims to "reinvent the drum 'n' bass wheel in the Big Apple" with a night of, well, drum 'n' bass. But fine drum 'n' bass it is, with rotating residents Dara, DB, the Mathematics trio, Know:El, Clever and Sibsonian rinsin' it out and the occasional top guest dropping in for a visit. And tonight the crew has outdone itself by booking one of the d'n'b world's best DJ-production teams—Marky & XRS—to tickle the Technics. The Sao Paolo–based pair (who are touring in support of the recent In Rotation LP on Inner Ground Records) inject a healthy dose of Brazilian sounds, jazz and funk into their beats, smooth enough for them to score Top 40 hits in the U.K., but still tough enough to pack a dance floor. Know:El and Direct Drive's DJ Seoul complete the lineup. We'd get here early for this one, as it's likely to be packed. For more information, check out www.sullivanroom.com.
