I downloaded two albums from The Kleptones today. I saw a reference to the remix album A Night at the HipHopera which I, being a big Queen fan, could not resist. While I was at the page, I saw the link to an album I had never heard of, Yoshimi Battles the HipHop Robots. Both albums rock completely. It doesn't hurt that I love the source material (for the instrumental tracks, at least) in both cases. I recommend each.
