Dream Theater guitarist John Petrucci was interviewed backstage in Vienna, Austria in February; the clip has finally made it online, and can be viewed above. He discusses the band's first-ever Grammy nomination, the changes in their set list as they incorporate tracks from On the Backs of Angels (and how they put the set list together), how the bandmembers remember their insanely complex songs onstage, and much more—it's a nearly 18-minute interview. Watch it now!
