A-Z was a solid record, as was KOM, but neither hit me like Fates does. A-Z was closer. I'm not a fan of Overland's voice. I think the music of KOM was really cool, but the vocalist has to connect with me. Just not a good pairing to my ears, but I can hear why folks like it.
Agree with WM about Tuesday the Sky. I think that's a very niche audience for Jim, but I dig it a lot. It's background music for me, mostly, but I feel like that style is really where Jim's passion is.
As for the future of FW, Ray has been pretty adamant in all interviews that Jim has said he is done writing for FW, and any further questions about that have to be directed to Jim himself, because Ray can't answer for him. But it's also very obvious that Ray wasn't in favor of ending FW. It just is what it is. Jim's the music writer. And if writing in the FW "box" (as wide as that is) isn't appealing to him, I get it.
I still don't think LDGN is as powerful as Theories. I think FW really accomplished the career-spanning record with Theories, and LDGN is an extension of that, which has some great moments, but not as good. I think it's just like how Inside Out was more of a continuation of Parallels with some minor differences. IO is a good record with some outstanding work. But it felt like a continuation of Parallels.
So as Goo says, until Jim is inspired to "reinvent" Fates' sound in a way that is still definitively "Fates Warning," I don't think we can expect anything. That said, I am looking forward to all the projects Jim has going on, and getting my hands on Ray's new solo record. Mike Abdow is tremendous (his solo catalog is brilliant), and I'm really glad he and Ray have blossomed as a writing team.
