I am on vacation and have a spotty connection, but I’ve found a few gems whilst poking around. Go away and see!
Amanda Palmer has released a so-cheap-it’s-basically-free (pick your price starting at $0.84) album of Radiohead covers on the ukelele.
See Green covers LCD Soundsystem’s “I Can Change.” (link)
Allison Crowe is a great artist, and there’s a very eclectic collection of her covering various folks at Cover Me, including the Rolling Stones “Shine A Light” (one of my top 10 favorite Stones tunes). (link)
