Marshall Harrison: the hermite-lindemann transcendence, all in black and white

As a thanks giving present Marshall has taken some time to upload his piano videos. I just can't fathom how Marshall can play both the piano and guitar to such a high level. I particularly liked Marshall's comment on the video Carmen Fantasy - Vladimir Horowitz by Bizet:
I promise to stop bothering my guitar fans with piano music. Just lemme upload a few more then I'll be done with those for good...promise.
But it seems that guitar fans are just as impressed with these as his guitar playing. Enjoy!
