The atmospheric instrumental trio Square Peg Round Hole are celebrating the release of their new album Juniper with a show tonight at MilkBoy. The sound is built around tight, intricate percussion, be it the super technical drumming, dueling vibraphones, or other found sound. Reminiscent of The Album Leaf or Lymbyc System, the group's latest effort succeeds with complex, driving undertones and dexterous melodies that carry the listener through. The songs are nimble and jazzy, calming while expressive. Slated for direct support is Philly’s own Moon Bounce, a funky Martian who makes R&B from the future, with his silky, theatric voice and sticky sweet synth lines. The energetic grooves fly in and out of frame, turning on a dime at any moment, making for a manic, but extremely fun experience. Also on the bill this evening will be the experimental pop of Son Step. MilkBoy, 1100 Chestnut St., 8:30pm, $10, 21+ - Adam G.
