Great band. Two of the guys are from this area, and they were originally known as Mosteller (the last name of their lead singer). They changed it to Carrollton after they got signed, a reference to the city in Kentucky that's halfway between Cincy and Louisville (the other two band members live in Louisville).
Apparently they gained quite a following as an independent band, even getting airplay on our local Christian station (which I rarely listen to).
They opened for Jason Gray when he played here at The Underground back in 2012, and apparently Jason's label liked what they heard, as the band announced they'd been signed 6 months later.
