The past couple years, the Mae version of Carol of the Bells has been in the Christmas rotation on one of my favorite radio stations. In my opinion, a new classic.  Their jazz meets rock interpretation spinkled with avant garde atmospherics perfectly captures the haunting vibe of the song adding their cool sonic signature to the tune.  Check it out over at last.fm.
