i didn't read this until after the show aired, and i only caught a small segment, but i was pleasantly supprised by how good some of the acts were.
I saw 2 that we will no doubt be seeing more of....Franklin Bridge, who reminded me of one of my favorite 70's bands Tower of Power, and a country -rock crossover act, whose name i didn't catch were also very accomplished.....
there was a brief run through at the end of the acts who were moved on to the next part of the contest, and "something" brothers were in there, so hopefully, congrats to your brother?
