I heard Eubie Blake a couple of times when I was living in Brooklyn. He used to perform at one of the band structures in the Prospect Park.

The Argerich video is a nice reminder of her work. I've heard her over the years, but on the radio. The videos are a revelation. I have a bunch of high-end CDs I got at a garage sale, when they thought no one would be interested so sold the entire bin of 300+ disks for $20. I'm betting I'll find some Argerich in there (but I'll have to search by composer). Whoever curated this collection of mine was, I think, teacher, probably university level. He/she had several performances of various pieces and I'm sure it was for comparison purposes. It's how one of my music classes was taught decades ago, a time-honored approach to teaching by comparison.
