Jake definitely brought it... And by "it" I mean an abundance of forehead. (It's okay for me to say that because I am a bald guy). Seriously though his playing sounds killer!
Yeah you can tell he's in there somewhere, but even his face has a flat affect. He just got too burned out, and I don't know if he could ever fully recover from it. At least he's trying though, so I hope he does well, and that the band gets better. They sounded like some drunk dudes on an open jam night to me honestly.
