Interestingly, Night Fly was an all-digital recording right on the heals or just before Brothers in Arms. Night Fly on a 3M digital tape system and Brothers in Arms on a Sony tape-based system in Montserat. I think George Martin may have had played some part in the Dire Straits sessions. 16-bit digital recording was nothing new since Jack Renner and Robert Woods had developed a 50Khz, 16-bit tape system in the mid 70s and founded Telarc which the made a big splash with Tchaikovsky’s 1812 Overture and the amazing cannon blast sequence for which at the time vinyl and R to R tape were the only available release formats.
@viridian is correct that Aja was produced by ABC/Dunhill.
Gaucho made extensive use of digital in the recording mixing and mastering of the final master tapes. I have an original 33 rpm from a Robert Ludwig lacquer which is easily as good as the AP UHQRs.
I’ve found that original pressings and early represses having been through countless copies never reflected the outstand production and engineering that was available on the original master tapes.
@rettrussell despite the untold losses of Universal warehouse fire there were still equalized copy masters and flat transfers in circulation and Donald Fagen appears to have known how to locate them or had in his possession these masters based on the recorded discussions between himself, Chad Kassem, Chris Bellman and Bernie Grundman when Analog Products was hyping the coming Release of the Steely Dan UHQRs.
