Check One Two host Mark Sovel throws together another eclectic bill tonight, courting the best in local talent for his much-venerated Viper Room weekly. A backup singer for LA indie-poppers the Bird & the Bee's, Alex Lilly uses her sweet, ethereal voice to deliver sexy electronic lullabies in Colorforms. Mod-rockers the Flying Tourbillon Orchestra, meanwhile, go heavy on the boy/girl harmonies while banging out a series of kitschy, stardusted beats. Balancing out the daisy-trippers, the notoriously sweaty Dengue Fever performs '60s-era Khmer-pop covers and Farfisa-drenched originals.
