Oh you must mean this one Steely , from CD 4FORUM , September 1975.
Richard Perry , is considered one of the "main men" in the Music business today. Besides the 10 gold albums and five gold singles that adorn his Hollywood Hills home, Perry is more known to the record community as the brilliant independent producer for Ringo Starr , Carly Simon , Barbra , Streisand , Harry Nilsson , and Ella Fitzgerald, among other artists.
Editor : Have you found any problems with CD-4 recording ?
Perry : Well, I'm just beginning to get into it myself but I haven't found any problem. It's just a question of starting to explore the resources available with CD-4.
Editor: How do recording artists feel about CD-4? Do they like it?
Perry : They seem to like it tremendously . I know that one night while working on Carly Simon's "No Secrets" album , we were listening to one of the most driving, up beat tracks on the album and there were quite a few people in the studio at the time , and we had the whole thing playing back in four-channel .
The room started lifting...and it was one of the first times I had heard something back in four-channel that I was working on. I had done some Barbra Streisand albums in quadraphonics , but that was matrix and I was not happy with the results . What I heard made me really believe that CD-4 is the only system to go with.
Editor : Do you decide if a record is matrix or CD-4?
Perry: I have limited decision whether it's CD-4 or matrix . It depends on the recording company and their commitment . In that case I can make the decision. Rarely can a company put out a four-channel product unless I sanction it and unless I do the mixing. At times , I might be too busy to do it or they tell me too late to mix in four-channel. If I make it my business to do something in four-channel, it will come out in four-channel.
