if it's gospel, and there is a damn preacher within 500 miles of it who has 'involvement', try to keep your distance from the damn preacher. i no longer want anything to do with a group with a preacher in it.
as far as gospel, if it is traditional gospel, it's like the blues somewhat. if it's 'the new stuff' (aka, like in the last decade or so), it's alot more like rock. some of the stuff is enjoyable, some not. note that my experience is...some of the young people want to exactly replicate the cd on the new stuff...there is no room for interpretation or change.... young people can be really closed minded. your experience may be very different...i wonder to myself if some of those kinds of people are control freaks first, and musicians a distant second, or third or....
have no way of knowing the makeup of this group you're considering. i hope your experience is way different than mine.
