If you are one of those people, who thinks they know a little something about blues, folk, gospel, jazz, or rock music -- then you will want to check this message board out!
If you are a musician (aspiring or otherwise), whose music falls into one of the aforementioned categories, you will also want to check this forum out. The depth of knowledge is amazing!
The community is close and loving, as well. As an aspiring harmonica player, I have learnt so much. If your question happens to be within those broad fields, you will almost certainly receive a detailed response. I've been posting for a while.
