I really like ADTOE despite what I say about the wankery and such. When that's not going on, its very good. Same can be said about most other DT albums. So I don't know what i can say I want to hear next from them.
I would like to see them branch out more from their traditional sound. Like when I put in an album like ADTOE and the first song begins, you know immediately that its DT, and honestly when that happened it did not excite me. It was a more of the same old thing situation. You know exactly what you're in for (it did grow on me and now I enjoy it). Now its good for a band to have their own sound and style. But I want to see them change that sound more. Honestly, I think they should take inspiration from Awake because its their best album, it has a different sound and atmosphere, but also is recognizable as Dream Theater. I guess the last album was a step in the right direction, but not enough.
I'm not saying they should make Awake 2 (as cool as that would be). I'm saying they need to do something more unique, because nothing they have done since are what I'd call unique. And yea, something raw and dark like Awake would be amazing but I can't see that happening in a million years, which depresses me.
