A little somber and psychedelic for the Letterman audience? ...Maybe not - The Raveonettes are undeniably amazing. I can only imagine the pair's energy in person; I need to see them live!
Anyway, I fully recommend this "Aly, Walk With Me" performance (follow that link to watch the official music video); it's so trance-y and mesmerizing. And when they go all-out with the noise and distortion? ... I had no idea so much guitar-abuse went into that!
