Buffalo's Alison Pipitone is a straight-up, straight-ahead barroom rock 'n' roller. Her music is like a rough-and-rowdy, sawdust-strewn soundtrack for blue-collar romeos, and as she puts it, "Dancing Girls on the Tables." Some might call the music "Americana." I say we drop the "a" at the end. Let the folkies keep it. Pipitone plays sheer American music. You'll see.
