KEVIN BLECHDOM makes avant-garde music seriously fun and engaging while at the same time seriously disturbing. Blechdom, aka Kristen Erickson, melds electronic pop music shaped by heady academia and twists it into irreverent, Dada-esque weirdness and wide-eyed musings that are both beautiful and grotesque. Like the sound of deranged Muppets singing about heartbreak, self-discovery and nose jobs, Blechdom's songs are not meant for the faint of heart. For her show Wed., JAN. 14, Irene Moon opens. Moon hones the sounds of insects to create buzzing, droning vignettes that are filled with drama and hidden dimensions of organic/industrial plod. The World Provider and Judi Chicago also perform. $6. 9 p.m. Drunken Unicorn, 736 Ponce de Leon Place. www.thedrunkenunicorn.net.
