Being a huge Queensryche of days ago, I don't have any real interest in them with Geoff Tate and Chris DeGarmo gone. The new singer, as you say, "can bring it" for sure. Just not the same for me. Being a guitar player.(as most of us here are) I can honestly say that to me Geoff was, (for the most part) the face and sound of Queensryche. He was the only reason I became such a big fan of them. Moreover, I always found myself, (for the most part) listening to the bass lines and drumming over the guitar playing.
Saw them a couple times. First time opening for Dio and the second was opening for Metallica on the first world tour of "And Justice for All". Memorable.
