I was fortunate enough to see Dennis perform with symphony in Kansas City last March, and even more fortunate to meet him after the show.I really can't say that I've been a Styx fan for well over 20 years because I was barely two by then. Still, I've been following them for a little while now; definitely long enough to know that Dennis was the heart and soul of Styx.This album takes some of Styx's best songs, lesser known ones, and Dennis's solo work, and puts them in a new light. It's incredible. Another reviewer mentioned that you don't know that Tommy isn't up there; it's true, nor do you care. Dennis is doing what he does best, with some of Styx's best work.I saw Styx, with Gowan, a few months after this, and it was clear to me: Dennis was the heart of Styx. There should be no doubt about it. If you are a fan of Styx, Dennis or classic rock, this album is a must have.
