Last night Nathan Williams brought his depressing yet catchy tunes to late night telly with his band Wavves. Bringing along a performance of "Demon to Lean On" to the Ed Sullivan theater and the Late Show with David Letterman the performance was raw and on point. The track features on the newly released album, Afraid of Heights. When the guitars are left to let rip this performance rocks, but I'm not quite sold on Nathan with minimal backing, maybe it was an off day. Still rather enjoyed it though. See what you make of it above.
