Dream Theater have made the stems for their current single, "On the Backs of Angels," available to anyone who purchases their new album A Dramatic Turn of Events (and that's quite a few of you so far). All you have to do is validate your purchase through the widget on Dream Theater's website. This is good for physical CD purchases as well as iTunes downloads.

Dream Theater will be on tour in North America starting this weekend, with Trivium in support, so visit our tour page to find a show near you!
