I totally agree with them, i've tried to play some of Dream Theater song (as i am a big Dream Theater fan), but it is virtually imposible to do what he does. His speed , his peeking technique, i mean, c'on you gotta love him. And it is not just Petrucci it is the whole group, they are amazing, Rudees in the keyboards, Portnoy on the drums, John on the bass, Petrucci on the guitar and Labries vocals. They all together play one of the most amazing music ive ever heard. Falling into infinity is another great album. I love it!!!!!
