Welcome to the jungle...and the drum and bass. Solar Flow, Saturday, August 31, at Boulder's Trilogy Wine Bar, is the first installment of the Rocky Mountain Turntable Lab series and promises a little bit of everything. The performance features DJ Jayem Cain of Motion for Alliance, a band described on the Web site www.mfacentral.com as "live electronica, technorganica" and "musical post-modernism." Lofty words for a spinner who rocks the floor with his hip-hop-influenced, jungle-jamming beats and trance-like grooves. Saturday's show might well be a preview of bigger things, as Cain will be joined by Sound Tribe Sector 9's "vibrational alchemist" Saxton and MC Scottrohedron. Sounds technorgasmic!
