Maine-based sound artist JASON LESCALLEET makes music from things that don’t work like they’re supposed to, using wrinkled, twisted tape, old reel-to-reel recorders, and other audio equipment scavenged from thrift stores. “I enjoy the sound of decay,” he told the Wire last fall. His most recent recording, last year’s The Pilgrim (Glistening Examples), infuses what might seem like a cold experimental aesthetic with a poignant dose of emotion. The album–an LP plus a CD–is a tribute to his father, who died of cancer in the fall of 2005. Side A of the vinyl is a performance recorded just after Lescalleet learned of the terminal diagnosis; he opens the show by reading an e-mail his father wrote about his music, a hitch audible in his voice. On the flip is a raw recording of his last verbal exchange with his dad, who speaks in an exhausted murmur. The music on the CD is all low-end rumble on the verge of disintegration–at once serene and harsh–and the context provided by the LP makes it thrum with sadness and anger. Like Lescalleet, his collaborator on Annihilate This Week (Brombrom, 2006), Sacramento’s JOE COLLEY also makes music from sound in various states of disintegration and distortion. Tonight Lescalleet and Colley play solo sets; on Saturday (which is free if you go Friday) they perform as a duo. a 9 PM, 6Odum, 2116 W. Chicago, 312-282-7676, $12. A –Peter Margasak
