I'll chime in here.
At least on the boys side, I think this is maybe the most unique group they've ever had.
Paul, Jacob, Casey and Brett are all very much their own artists, and all very different. I don't know if he'll go very far, but Scotty is certainly different than anyone they've had on before, as an old-timey kind country singer.
I wasn't a big Lusk fan until tonight, but his performance was all kinds of great. He can go a little run crazy, but he reigned it in tonight and his voice is just so smooth.
Other favorites are Casey Abrams (I love how confident he is) and Robbie Rosen (had some rough patches tonight, but I love the tone in his voice.
