Interesting, from wiki
Band leaders Becker & Fagen said they were dissatisfied with the album's sound quality because of an equipment malfunction with the then-new dbx noise reduction system. The damage was mostly repaired after consulting with the engineers at dbx, but Becker & Fagen still refused to listen to the completed album
That’s sad. I love the songs on the album. I remember when DBX came out. And Dolby! Remember Dolby?
They were perfectionists, what can I say?
