I listened to the first two and yeah, really enjoyed the playing and tone on them.
I can understand what you mean about people being put off by the Christian theme.
Personally, it's not my scene, but I do think the Yanks really do know how to do Gospel etc. so much better than we do. Everybody from the musicians to the choir, the preacher to the congregation. They all completely immerse themselves in it. When I see anything in the UK, it all looks a bit stilted, almost as if they're meant to look like they're really into it, yet at the same time still being a bit reserved as if clapping hands or holding their arms in the air is enough.
