First off, while only Chris could say for certain, I'm pretty darn sure DeGarmo would want nothing to do with current Queensryche. I'm sure he's happy for Michael and Ed if they're happy, but I don't see him being remotely interested.
Second, the hate for Hear in the Now Frontier needs to stop. I get people (looking at you, Tim) not LIKING Hear in the Now Frontier. I totally do. But if you're a Queensryche fan for the entirety of their run with DeGarmo, that is what they did - change their sound every record incorporating what they are learning as songwriters, what styles are popular and influencing them. Even as much as people credit Rage for Order as this forward thinking album - QR was influenced not just by goth and vampire stuff as an image, but musically as well. As DeGarmo himself said - (paraphrase) nobody's original, everyone's uniquely derivative. DeGarmo, as QR's primary songwriter in the 90s, was listening to what was local, and he was friends with guys like Cornell, Cantrell, etc. If you listen to HITNF, you can hear the influence a record like Down on the Upside from Soundgarden had on the direction of HITNF, plus DeGarmo's own evolution of a songwriter.
I get it if people don't like that style, but as the years have gone on, I really have come to appreciate HITNF a lot. Sure, there is way more filler than usual (a product of the experiment they did of not over rehearsing the material and just going in and doing it more spontaneous). But the record is completely full of all the usual Queensryche hallmarks. It is, like all the albums before it, an evolution of sound by Queensryche. And I really enjoy the variety.
re: Tate-DeGarmo - those two are the soul and heart of the band, with Wilton being the balls. Wilton didn't evolve as much as DeGarmo did as a guitar player. You hear it in his solos and his riffs. But that's what made him being the third key songwriter in the band so important. He kept the metal riff a big part of Queensryche, and I'm so glad he did. He got a bit phased out on PL and HITNF, but on those original lineup songs from Tribe (Open, Desert Dance, Falling Behind, The Art of Life, Doin' Fine, and Justified), those main riffs in Open and DD are absolutely his to my ears. And the rest of Tribe (the non-DeGarmo stuff) - again, a lot of that is Wilton.
People can talk about the current version of QR and love it, and I am happy the band is happy and fans are diggin' it. But they are a COMPLETELY different entity. It's like listening to a completely different band to my ears.
