Probably should have called this "Getting Bluesy", but I think of it as "Getting Church". African American Church musicians are some of the funkiest, bluesiest best players I have ever seen. It's incredible what some people get out of church. I would never have gotten that kind of musicality out of my church. The music was lame as I remember.
I'm not even religious, but I have gone by some churches and wanted to go in and listen and watch really bad!
So.... Get Church.
