One of my favorite things is when musicians do a cover of a song that I love. The result is often completely different and completely awesome. Here are some of my faves:
Crazy | Gnarls Barkley (original) & Ray Lamontagne (cover)
Hallelujah | Jeff Buckley (original) & Justin Timberlake, Hope for Haiti (cover)
Fields of Gold | Eva Cassidy (original) & Sting (cover)
Think It’s Going To Rain Today | Randy Newman (original, though this performance was more recent) & David Gray (cover)
And It Stoned Me | Van Morrison (original) & David Gray (cover)
Sorry for the visual and sound quality of some of these, you take what you can get with YouTube.
