Remember Pinebender, that Chicago three-piece that formed in 1997 and then dropped some heavy experimental-rock albums on Lovitt? No? Anyway, they’re playing a free (but not 90s-nostalgia-free) show Saturday at Quenchers (2401 N. Western). Sssnake and Euphone will open, starting at 9 PM; Pinebender’s set is at 11:15 PM.
