Smart of Casey to do the shout out to Esperanza Spalding. I see Casey having a ton of fun and earning a decent living playing small clubs.
James is a hoot! I hope he makes the finals because he makes me smile.
Sorry, but I still don't get Jacob. It seems that he's lost between owning the gospel singer label and trying to be something he's not. Total turnoff for me.
Same with Scotty. Some music teacher must have told him to hold the mic so people could see his face. Either that, or his music teacher admired the song stylings of Dean Martin. I can't get past the cheezy performance level.
The rest, meh.
My B3 would be Paul, Haley and Jacob.
