I always enjoyed liner notes as well. I'm one of those who would ask, especially in the '70's, "How did they do that?" When a new Wendy Carlos album came out, I would have killed for more details on how the big Moog 3 modular synthesizers were used. There are many artists today, like Aphex Twin, or Sleep Research Facility, who give no hint as to their instrumentation, other than, 'some very powerful software.' That just piques my interest more. Details, man!
Jan Hammer released an album called 'The First Seven Days' in '76, I believe, and while it listed the instruments used, there was also the disclaimer, 'For those concerned: there is no guitar on this album.' Interesting that he wanted to emphasize that point.
