I've been a big fan of the Piano Guys since I stumbled on this amazing duo on YouTube. Their story is really pretty amazing. A guy who plays the piano and another who plays the cello get together to put together an interesting mix of classical and pop music, add some video, and boom you've got an internet sensation. Now they're doing concerts in major cities and Sony has decided to pick them up. Last night I had a chance to see the Piano Guys live and they didn't disappoint. It was a great concert. You should check them out. For you Les Mis fans out there - you'll really like this video.
