Jars of Clay and Third Day are big Christian bands. Both have had some cross over success. I'd classify Third Day as Southern Rock, Christaian style. Jars of Clay, hmmm, not really folk, I guess I'd classify them as Alternative Rock, Christian style. Switchfoot is more or less Alternative Rock, but not really Christian, in that their lyrics are not Christian, but positive, maybe a little like Collective Soul, but more mainstream. They've had a big hit lately, "This is Home", it's from the movie soundtrack for Prince Caspian, The Chronicles of Narnia 2. Robert Randolph is a black fella who plays a wicked steel guitar. I had never heard of him before, but we loved it! His music is bluesy, rock, funk style.
