Excited to hear something less...ambitious, I guess. The Color Spectrum did absolutely nothing for me, and I think it's good that he's taking a break from the series of acts.
Beyond stoked, Casey can do no wrong. I think this should be a lot more fun for him as well, since he doesn't really need to stick to guidelines for this.
I typically enjoy albums more when they have a particular theme or concept, so it's kinda disappointing to hear this. Hopefully it'll still be a cohesive piece of work, but I don't have any doubts because Casey is the man.
