After four albums on Touch and Go, nouveau French nymphs Sierra and Bianca Casady jumped to Sub Pop for May's Grey Oceans, a waking dream visited by a weird cabaret of stage-show orchestration and electro beats. Opening is bounce rapper Sissy Nobby, whose ridiculously riled-up "Beat It Out the Frame" tops the shortlist for best NOLA club popper of 2009. Tickets $15 advance purchase, $18 at the door.
