I was having trouble coming up with the RIYL for sure. I just couldn't think of any bands that they really reminded me of, so I based it off of the music rather than vocals. Chandler has a voice that stands out and I don't think I'll be able to compare his voice to anyone else.
I agree with this. I'm picking up some foo fighter sounds in some of his songs. It's weird because right when it is turning really rock sounding, it turns back to a punk or emo sound. I love it, a great mix of genres I think. Good find!
