Earshot: Andy Clausen & Sjenka

Presented by Earshot Jazz. Although still a year shy of high-school graduation, Andy Clausen has been making a big splash on the local scene. The Roosevelt High stand-out plays trombone in the school’s acclaimed jazz band, composes for his own sextet, and performs on laptop in the electro-pop band This Sporting Life. Tonight Clausen performs with Sjenka, his ambient improvising group. He performs on laptops using such devices as “musolomo,” a computer program that allows performers to sample and recombine sections of performance. His co-conspirators in provocative creation of the new and the fresh are two fellow Roosevelt students, Corey Dansereau (trumpet, vocals, electronics) and Max Williams (guitar, electronics), along with 2008 Roosevelt grad Xavier McHugh, who is Berklee bound, on percussion. Luke Bergman, who performs alongside Cuong Vu in Speak, joins them on bass.
