I don't know, just couldn't get into them. Tried listening to the albums a few times and didn't really enjoy. Hearing live (twice), just wasn't a fan of the quick pitch change he does at the end of his lines. I've heard people compare them to Citizen, who I do like, but I haven't seen them live either so I can't say I'd enjoy in the same setting. I'm a huge fan of Kevin Devine too though, maybe I am a bit jealous they got to play second. :)
I would just give Separation another go. So many feels. I agree though with the live vocals :/. That show was the first time I really heard Kevin Devine and I really, really liked him.
