Or Lovin’ Spoonful.
Back on topic, since I’ve been pondering this.
I think we can (sorta) agree about the years that were Peak YR, i.e. somewhere from the mid 70’s and ten about ten years. And what happened during that time was that studio equipment got magnitudes cheaper and more powerful.
When Floyd and Parsons recorded Dark Side of the Moon in the EMI (now Abbey Road) studio, they had to contend with 16 channels. The nature of the album required them to to multiple overdubs and down mixes. I’ve seen a couple of documentaries and all five of them were on the consoles and other paraphernalia trying to juggle tape loops and such as the VCS3.*
In the documentary History of the Eagles, curmudgeon Henley complains about recording with producer Glyn Jones. The producer used three mics for the drum set and thought that was enough and according to Henley Jones said that it was good enough for Bonham, so Henley should hit harder.
All this is to say that by the end of the decade 32 channels was common and for the biggest productions, maybe even 48 or 64. This meant that it was possible to put a mic on each drum (so snare, toms, kick and two overhead, IOW at least six). Each channel could then be fiddled with to achieve what was consider the optimum sound. The floor toms a little to quiet? Up the gain. More oumph to the kick? Run that alone through some processing box (often a reverb).
And so back up singers had their own channels, horn(s) had theirs, bass, rhythm guitar, lead, keyboards, vocals… plenty of channels to spare and each could be tweaked in myriad ways.
So they did. And the result of them playing around gave us a sound that was too polished, too perfect and the end result felt… well whatever pejorative term one would use to describe YR.
Case in point, and I’ve posted this before. Christopher Cross can really… well, shred his guitar. If you listen closely, it’s buried deep in the mix of Ride like the wind. Rick Beato did a video on this and later a follow up with an interview with Cross. Well worth checking out.
