Akin to all the above, back in the early 1960s, World Record Club were issuing 12" Lps of Classical music which had been produced using a variable width (if that's the right word') groove spacing, wide for loud passages of music, narrower for quieter sounds -this gave increased playing time per side. Somewhere I may still have the article(s) from the WRC Magazine which described the process.
