Here is a UStream cast by pianist and educator Dave Frank on Frank Zappa’s music. The session starts with some solo piano playing of none Zappa material (really nice), followed by some interesting analysis on Zappa’s tonal, modal, and atonal music. The analysis is formalist in nature, so most of the discussion concerns how the music works, not its ‘extra musical’ meaning. Really worth a watch if you are a musician interested in musical analysis. Pieces discussed included Peaches and Regalia, Watermelon in Easter Hay, and Envelopes.
