MOG

(I'm not sure that the tracks i uploaded for this post are going to play. If not, you can hear the Ramones track here, and the Steeleye track here.) I did a post in which i touched (sort of incidentally) on the way stereo was handled in Sixties record production (mostly badly).

Spike made a comment, leading me to make one in reply, and, eventually, this was the eventual result:

Two of the evillest stereo tricks i've ever heard assume that someone, sooner or later, will be listening with headphones on.
The track with this post is the last minute of Steeleye Span's The Weaver and the Factory Maid from the Parcel of Rogues album. (Which, incidentally, takes its title from Robert Burns...)
The very first time i heard this was on FM radio, with headphones. And All! Those!! Voices!!! were inside my head!
I had a chance, a few years back, to ask Maddy Prior how many vocal tracks they piled up; she couldn't recall.
