The Philadelphia band Sheer Mag walk an interesting line. They play bluesy, choogling, Camaro-revving classic rock — straight-up Dazed & Confused-soundtrack cruise music. But they’re a DIY punk band, so they play it scrappily and noisily, with the lowest fidelity you can imagine. That’s a tough combination to pull off, but Sheer Mag do it, thanks largely to the huge voice and charisma of frontwoman Christina Halladay. The band’s new 7″ EP II is out now, and we’ve already posted “Button Up” and the “Fan The Flames” video. But you should really hear the whole thing, and you can do that below.
