I just found out that one of my favorite jazz artists is going to be on tour, Brad Mehldau.  I saw him and his trio a few years ago and it was one of the best concerts I've been to.  He does really interesting covers of songs by Radiohead, and The Beatles to name a couple.  He also has his own compositions which are quite awesome.  Here is a link http://www.youtube.com/watch?v=hMKdsY8_8Yc  check out his stuff.
