Seriously. Listen to this cover of Radiohead’s “Optimistic” and see if you can tell who it is. I happen to think it’s a great cover, and was totally shocked when I found out who it was.
By the way, I heard this on Brian Ibbott’s excellent Coverville podcast. So, if you listen to Coverville and heard it there too (or if by some unbelievable coincidence you own this album), no fair guessing. And if you didn’t, well, you should be listening to Coverville.
