Just picked up tickets for his show in Chicago in October as well.
I've seen them in Chicago before at UIC. They were really good. Granted, this was after their self titled album. I was not a fan of 22 A Million at all. This newest album though, I really like.
Also, I saw keyboardist, backup vocalist, multi-instrumentalist S Carey in a freaking living room show in Valley Junction. I literally sat on the couch with him and had no idea who he was.
