For a certain era, Friday nights at Michele’s Restaurant in Santa Rosa meant pulsating rhythms and gyrating bodies. Decadance, the long-running dance club, was the hottest thing around in local DJ culture. After a hiatus, the night returns in full style at the Flamingo Hotel this weekend, featuring “the Bay Area’s most wompy duo” LowRiderz, An-ten-ae and resident DJs Zak Darling, Damian and Malarkey. For those who want to relive the glory days, Decadance’s Facebook page hosts over a thousand photos from the Bush years; for those eager to step into a new era, be there Saturday, Jan. 21, at the Flamingo Hotel. 2777 Fourth St., Santa Rosa. 9pm. $10. 707.545.8530.
