Simply the best piano masterclass in all of youtube. Really instructive and lots of food for thought, especially at the very end when Maestro Sebok talks and DEMONSTRATES like no one else his marvelous ideas about whole body participation in piano playing.
My teacher studied with Sebok and I've heard all sorts of remarkable stories. After seeing this video, he has lived up to all of my expectations. I used to believe that my teacher was exaggerating these stories, but he really was that brilliant and inspiring.
