I went to a Big House concert a few weeks ago, and now I'm a devoted fan. (I got to meet them, too!) These guys are great- you have to go see them. If you haven't heard their hit single "Cold Outside" check out their debut album (also titled 'Big House') at a store in your general location.
Big House is: Monty Byrom, David Neuhauser, Chuck Seaton, Sonny California, Tanner Byrom (Monty's brother), and Ron Mitchell. I haven't got a picture yet on this page, but I'll get one soon and in the meantime do yourself a favor and get out to one of their concerts.
