Four takeaways from Wavves’ performance of the Afraid Of Heights single “Demon To Lean On” on last night’s episode of the Late Show With David Letterman, which marked the band’s late-night TV debut: 1. Nathan Williams has a better live singing voice than most of us have given him credit for. 2. Some Letterman producer should’ve forced the audience to mosh; a Wavves performance with no moshpit just doesn’t look right. 3. I would be a happier person if I owned bassist Stephen Pope’s tie-dyed, sleeves-cut-off Justice For All Metallica T-shirt. 4. “Demon To Lean On” is easily one of the three or four best songs Wavves have ever recorded. Watch the performance below.
