Sluts and sinners, rejoice. Michael T and Theo’s raucous, rowdy party Rated X is back. The bash—where dancing in your panties is not only encouraged but rewarded—jump-starts the opening of the new Scenic (now known as Club Midway). Expect the usual antics from Peppermint Gummybear and the debauched children she picks to participate in their top-of-the-hour Hot Body Contest. In between, dance on Kevin Carpet to G N’ R, Blondie, and Bauhaus. The reopening also marks their three-year anniversary. I’m praying for your lost souls. Sat @ 10, Midway, 25 Ave B, 212-253-2595

Pier Bucci’s Familia is like a ray of sunshine on a cloudy day. (Was that corny?) I may be, but he’s not. Late last year, he sprung a glorious shimmery techno record on the world—filled with reverb and enough pretty melodies to fill your dreams till eternity. The Chilean producer shares a South American sensibility with fellow Chileans Ricardo Villalobos and Luciano (he also co-produced Lucien-N-Luciano), but owes more to the head-tripping, gravity-defying world of tech-house that Swayzak used to inhabit before they got so obsessed with becoming pop stars. He plays live with his other project, Mambotur, which includes Venezuelan singer Argenis Brito. Thu @ 10, Love, 40 W 8th, $15-$25

More Latin love—and just in time for Cinco de Mayo. The Nortec Collective exploded a few years ago with the release of The Tijuana Sessions, Vol 1., but it was Fussible’s fantastic “Casino Soul,” with its horn blurts and crescendos, that really nailed them as the next big thing in dance music. The sound was Latino without resorting to simple salsa clichés. They may have crossed over to the mainstream with a remix appearing on Beck’s latest, Guero. For this show, the Tijuana-based Nortec DJs back Columbian electronic duo Monareta. Fri @ midnight, S.O.B.’s, 204 Varick, 212-243-4940, $15-$18
