I only have Rhythm of Time. It's a great album, Screaming Head is as of now my favorite. I like the way he uses the synths and all those keyboard sounds. MP was right in saying DT doesn't even scratch the surface of what this guy is capable of.
if theyre so aware of that, why dont they scratch the surface???
Because Dream Theater isn't JR's backing band?
by this logic, Dream Theater is really Petrucci's backing band, at least since ToT
im just saying, and i know he contributes plenty in the band, but ive heard the keyboard parts from the stems of BC&SL and he does fantastic stuff, but the mixing is just pushed too far back on the album. And even then, his potential is not reached for, again, since at least ToT (Octavarium was the exception, his keyboards flourish on that album)
