Have you ever heard the sound of one washed hand clapping? No; a hand cannot clap itself, or otherwise, and the sound of fingertips barely tapping its own palm cannot be construed as a clap - it is but the sound of juvenile contrarianism.
Ahhh, band PR emails...
Washed Hands is a psych synth pop group from Montreal. That's in Canada. You can download their PWYC album at their bandcamp site here. Dig this song, "Datsun Dream, 1980:"
