After years of not listening to any Dream Theater, the new stuff brought me back to the band. Granted, the new stuff hasn't really clicked with me, I am enjoying some of their older stuff again.
Namely, Octavarium (which I previously didn't like), The Way It Used to Be...But man, what's really got me right now is the "Unplugged" version of To Live Forever. That build during Sherinian's solo is just wonderful until it really opens up. I don't think they write like this anymore.
