You're welcome! :-)

One of my favourite piano players - I know he isn't a blues player, more jazz - is Fats Waller and my fave track of his is Twelfth Street Rag. I have it on repeat. The more I hear it the more I love it. I even had it as our doorbell song for a while but then I wouldn't care about answering the door because I was too engrossed in listening to the tune again. :-D

Some of his other piano tracks which I love are the sweet and gentle, When Somebody Thinks You're Wonderful, the slow and beautiful Fats Waller's Original E-flat Blues, and Riffs etc.

You might not easily find videos of piano players from earlier decades, so some videos of more modern players might be available and some of them are tuition videos too.
