So, I positively DESPISE U2. Hate on me if you want, but I just can't stand them.
I'm also usually not a fan of covers, but every now and then, there comes a banger! Saul Williams covering "Sunday Bloody Sunday" is an absolute masterpiece (even though it technically isn't his).
You should check out all of Saul Williams' stuff. His live poetry, his books, his music. He is a very brilliant man.
