Scorcese documentary on Bob Dylan

Has there ever been a rock star as contrary as Bob Dylan? When taken for a folk singer, interpreting traditional songs, he started to write his own. When taken for a topical songwriter who would dutifully put his music behind party-line messages, and praised as the spokesman for a generation, he became an ambiguous, visionary poet instead. And when taken for an acoustic-guitar troubadour who was supposed to cling to old, virtuous rural sounds, he plugged in his guitar, hired a band and sneered oracular electric blues. That's the story told in two overlapping projects: the two-CD set "No Direction Home: The Soundtrack", to be released today, and "No Direction Home," a documentary directed by Martin Scorsese that will be released as two DVD's on Sept. 20 and broadcast on the PBS series "American Masters" on Sept. 26 and 27.
