Transformer, Lou Reed, 1972 and Exile on Main St., The Rolling Stones, 1972

I see parallels between Transformer and Exile on Main St. Lou using strings, piano - the Stones using horns and adding other instruments. Recall that Exile got bad reviews because it was not guitar driven and buried Jagger's vocals in the mix! (The 2010 reissue cleaned it up too much! Keith didn't like it.) 

Artists should take care with their old work.  Remember how the painter Gully Jimson (in Joyce Cary's wonderful novel The Horse's Mouth) was trying to get people to forget the Sara Monday paintings (while simultaneously trying, without much success, to wring money from them).
