Band whose singer sounds like Aaron Weiss? (Mewithoutyou)?

I heard a song on Sirius XMU radio the other day, I can't remember what it's called, who it's by, or any of the lyrics... BUT! I do remember that for the first few minutes of it the lead singer sounded remarkably like Aaron Weiss of Mewithoutyou. It was pretty slow in the beginning, and then really picked up at the end. I realize how vague this description is, but does anybody have any clue as to what I'm referring to?
