Arc in Round will be celebrating the release of their new self-titled LP (due out June 26 via La Société Expéditionnaire) a little early tonight at Johnny Brenda’s. There is a sense of continuous forward progression in their sound as the futuristic tunnel vocals meld with electric guitar, bass, synthesizer and drums in a chaotic quantum leap of musicality. The individual pieces when isolated also have a unique quality: the pulsing synthesizer, the rapid-fire hailstorm on metal roof percussions, and the guitar ringing in a far-out place. However, the combination fits together like a jigsaw puzzle where odd pieces somehow meet at awkward angles to create a perfectly streamlined picture. It will be a packed evening of sonic experimentation as pals Tadoma, Pet Milk, Beige and Pink Skull (DJ sets) help make Arc in Round’s album release party a memorable occasion.
