As we all know, Dream Theater loves to show tribute to their influences as a band and they do them incredibly well. I came upon a poll somewhere that asked which songs they should consider, but I'm not sure if the poll would really reach the band, so I though here would be a good place to post ideas for songs. Even if we as fans don't know all the bands you guys listened to, it could be fun..
Now we all know DT has done many many covers, medleys, and even full albums during shows, so this thread is specifically for studio ideas.
Personally, I'd really like to hear them play some 'Time and a Word,' 'Caress of Steel,' 'Perpetual Change.' Any Yes or Rush usually will rock pretty hard.
