OK, that headline is kind of an understatement. Dream Theater is currently on tour in Europe, introducing new drummer Mike Mangini to the world and preparing fans for the release of their new album A Dramatic Turn of Events, due out September 13, and the response has been kinda rabid, actually - as is to be expected when it comes to Dream Theater.

They've only played two shows thus far, in Rome and Villafranca, Itally, and YouTube is already jammed with fan-shot footage of the band in action, including performances of their new single "On the Backs of Angels" (which you can hear here). Other fans have recorded their own cover versions of "On the Backs of Angels," which are also viewable on YouTube.
