Welcome to the Asylum

Be sure to keep your collection of Asylum Street Spankers records separate from your kids' copy of the group's "Mommy Says No!" album, with its songs "Boogers," "Training Wheel Rag," and, our favorite, "Sidekick" ("Every hero needs a sidekick," they sing, and we couldn't agree more). The Austin, Texas, acoustic-blues and roots gang is partial to Bessie Smith and Robert Johnson but mixes it up with original tunes, vaudeville antics, social commentary, great harmonies, and an instrument arsenal of washboard, harmonica, singing saw, and more. Sorry kids, tonight's show isn't for the booger bunch. 8 p.m. $25. Club Passim, 47 Palmer St., Harvard Square, Cambridge. 617-492-7679. clubpassim.org
