The tiny bit of Albert Ammons was great But let's face it,blues piano was pretty thin on the ground. There must be a lot of footage of blues pianists central to the music that they could have used. And if you're short of film clips, you could always play Jimmy Yancey and Leroy Carr records and have some different film images. Art Tatum Ray Charles, Nat King Cole Dave Brubeck etc etc, are all musicians I can enjoy, and all blues influenced, but they are not the core of piano blues. The the whole thing was a bit wide of the mark for me.
