Back when there were only a handful of U.S. jungle jocks, who were lucky to get small change to play side rooms, DB and Paul Morris bravely opened Breakbeat Science, the nation’s first all-jungle record store. Five years later, the shop’s profile has grown by leaps and bounds-their expanded selection (now including 2step and other variants of breakbeat) and popularity have led them to open a larger “superstore.” This week they celebrate with a party at P.S.1, and the lineup reflects their new, widened musical scope, with triple DMC World Champ and fellow junglist DJ Craze (who Time named the nation’s numero uno DJ) and 2step king MJ Cole, plus Breakbeat Science regulars, Dara, Reid Speed and DB. Saturday @ 3, P.S. 1 Contemporary Art Center, 22-25 Jackson Ave, LIC, Queens, 718-784-2084

Baktun owners haven’t wasted any time getting back into the club game: After over a year spent fighting to get a cabaret license, they’ve opened their doors and their amped-up soundsystem to an impressive roster of talent. The newest Baktun weekly resident is none other than New York house legend Tony Humphries. If Twilo’s closure inadvertently leads to better, smaller club nights, perhaps we should close all the rest down as well. New Yorkers should be so spoiled. NUTTZ, Tuesday @ 10, Baktun, 418 W 14th, 206-1590.

The best thing do when clubbing in New York, of course, is to avoid clubs at all cost, something the ingenious folks at Matter:/ Form figured out a long time ago when they started throwing boat parties. They’ve outdone themselves this summer, boosting their already ridiculous lineups about 10 notches. Two weeks ago, 400 dancing lunatics and one bald Richie Hawtin got jiggy with it in front of the Statue of Liberty; this week, minimal d’n’b technician-turnedhouse head Photek takes the Paddlewheel Queen for a spin. Get there early and make sure you reserve your tickets. Sunday @ 7, 23rd and the East River.
