Thrillhouse Records is the city's little record shop that could. In an era where the only news you hear about bricks-'n'-mortar music retailers is bad, Thrillhouse continues chugging along without a cent to pay its employees. The Outer Mission nonprofit is run by a passionate pool of volunteers, who stock the shelves with vinyl, CDs, and cassettes from bands like the Fleshies, Nodzzz, and Shotwell. Every cent spent in the diagonally shaped store goes back into buying more independently released product. Nearly every staffer doubles as a musician, too. Stepping into Thrillhouse is an important reminder that as the corporate dinosaurs of the record industry fall, punk-rock outlets prevail, based on that old-fashioned DIY approach that's been financially broke from the beginning but remains rich with enthusiasm.
