In a town besieged by dance-floor cheese, the Droog DJ collective is a breath of fresh cred. The trio of Andrei Osyka, Brett Griffin and Justin Sloe has been building a community of followers based on groovy, understated tech-house sounds and superlative afternoon poolside parties that have made the Standard Downtown's rooftop venue harder to get into than an Oscar party. Bouncing bikinis? Sure. But oh, those beats. Droog has forged a European-style outdoor season with its Culprit Sessions, which go monthly from April through October at the Standard — every other Sunday from 1 to 8 p.m. — and often feature the globe's most-wanted DJs, such as Jamie Jones. Be sure to check out the season-closing party on Oct. 14, featuring the sublime Guy Gerber. After that, the trio takes its party on the road to places like Spain's Sonar Festival and the DJ mecca known as fabric London. But we're told Culprit Sessions will be back like syncopated clockwork in spring. Check facebook.com/culpritla for the latest schedule. RSVP encouraged. 550 S. Flower St., dwntwn. (213) 892-8080, facebook.com/culpritla.
