The music is heavier than Clapton but John Petrucci is a master of his style.
I got a live show they made in japan on Video and Petrucci breaks into a amazing solo. Going from fast paced Yngwie style to some fingerpicking jazz licks. I had to rewind the tape a 20 times, that's what I like about him. He really is a versatile guitarist. Well, all the members of the band are amazing.
