The Mantles - "Bad Design" Hot off the heels of their Siltbreeze full-length, The Mantles are back from tour with a limited edition 7" on Slumberland/Dulc-i-Tone, and a great show Saturday night at the Hemlock Tavern (9:30pm, $8). Seriously, Mantles, Finches, Little Wings? That's a hell of a lineup.
