Figured I'd post a couple more of my favorites before the next post, which will be coming soon
Some instrumental ones here, basically Rodrigo y Gabriela are a Spanish-speaking guitar duo who do some great instrumental work, they've also covered Stairway to Heaven which is fantastic as well. I especially like Gabriela's technique of slapping the guitar.
And Chris O'Riley is an amazing piano player who actually has an entire album of just covering Radiohead songs. It's really great and I think an interesting take, and if anyone want's a link to it just ask
