By their fourth album, Steely Dan was Fagan and Becker and session musicians. Even Fagan and Becker didn't play on all their own songs anymore. This album is their sixth, and it has elements of R&B and funk, and is very jazzy. It's a classic album, no filler. The song "Aja" is a masterpiece on many levels.
I already own the box set, and wanted to upgrade to the remastered CD's because of good reviews on the "improved" sound. The remastering is subtle - the sound is cleaner, clearer and has more depth, but has retained all the dynamics without being overly loud or bright. However, without a hi-fi stereo system, I doubt most people would notice any improvement over the oringal CD's or the box set - previously released versions already sounded quite good. So, it's an unnecessary purchase for most people(hence, my reason for deducting one star).
The remastered version includes lyrics and extra running commentary, which is continued on each successive CD.
If you like this album, you may want to check out the DVD, "Classic Albums - the Making of Aja".
