I've never rally listened to Steely Dan, but recently on a plane trip I was listening to an excellent track on the in-flight radio only to find out afterwards that it was Steel Dan. The bass playing was excellent and it may have come from the Aja CD. Anyway are they any good? Is Aja their best CD, which appears to be the opinion of a couple of websites I've just checked out. How is Becker as a bass player, or was I more likely to have been hearing Chuck Rainey? I'd just like to get some TBers opinions on them.
