After watching a few other classic rock album documentaries, I wasn't expecting much from this Aja documentary. It turned out to be a surprisingly good review of the recording of Aja. Firstly, it was mostly the Steely Dan musicians Fagen and Becker along with studio musicians that provided commentary on the album, unlike other album documentaries that have mainly outside commentary from music critics. Also, there's alot of footage of a reunion of sorts where they play the music. The bassist Chuck Rainey, who made a major contribution to the rhythmic feel of the album, plays some of his bass lines solo. Fagen and Becker also comment on the instrumentation and performance of Aja while seated at a studio control panel making adjustments to hear the music parts in isolation. This is the best classic rock documentary I've seen on DVD.
