In 1991 I lived near a young jazz pianist, Mitchel Forman. I was interested in experimenting with some home video concepts and asked him to play a song that I could videotape. I was shooting using a ginormous s-VHS camcorder, and this was the home music video I created from that session.
It's worth noting that I wouldn't call this a "sketch," in that even though i was shooting with one camera, no mic, no lights and on my own, i was also directing my subject and had him play this song multiple times to get the coverage i needed. The s-VHS tape this cut was on was disintegrating even as I pulled the last bits of signal off of the tape. This is all that remains of the session.
