Steve Gadd did the Steely Dan Aja recording in one take according to Gary Katz who produced the session.
About 6 months later Katz was in NYC doing the final mix down of Aja at one of the recording studios and heard Steve was doing a session down the hall.
He asks Steve to stop in and check out the final mixing.
Steve listens to the recording and asks who the drummer is, cause he is a burning it.
Katz says it's you, to which Gadd said I am a bad motherf@@@ing drummer.
Apparently Gadd was pretty toasted when he did the Aja session.
Wish I could get that kind of toasted.
The ironic part is Becker and Fagen didn't want to use him because his back beat was suspect.
