When I lived in Kentucky in the 1980s, I had several opportunities to hear the Metropolitan Blues All Stars perform. The group members came from in the hills of Eastern Kentucky; they came to Lexington for concert performances (or to Louisville for Lonesome Pine Specials as in the 1987 one embedded above).
I particularly remember Rodney Hatfield's prolonged harmonica riffs, and I have an old VCR tape with Caroline Dahl really rocking the keyboard; I understand she later moved on to San Francisco for a successful career there. Here's her Boogie Woogie Piano with the Metropolitan Blues All Stars, recorded in 2007 (here's another boogie woogie performance, with Tom Rigney and Flambeau in 2007). Is boogie woogie still popular? (I don't know - don't get out much)
I wonder if any other readers here remember the group. Miss C?
After some internet searching, I discovered Rodney Hatfield playing with a group called Tin Can Buddha (profiled in this KET recording).
