Lynn at Reflections in d minor points us to In The Hands, a piano-music blog by Paul Cantrell that includes commentary on and recordings of piano music by Chopin, Bach, and Schumann, among others.
I was thrilled to find a recording of the Chopin's Étude Op. 25 No. 1 (in A flat major) here. I played this étude in high school (albeit not very well) and it is one of my all-time favorite pieces by Chopin.
