Dream theatre is home to an awesome guitarist (John Petrucci) and a similarly great bass player ( John Myung )
Give them a listen...as to what sort of music they play, I find it best described as a sort of classic metal with more mainstream friendly melodies etc...perhaps a pop-metal of sorts, although it is not fair to use that as a genre to describe them...Think Queensryche...With Balls!
Take a listen...They rock
