I'd swear Eno said Fripp's 'St Elmo's Fire' solo is a collage of tape snips
Saw Eno's 1979 "The Recording Studio as a Compositional Tool" tour, in Davis, California - I recall him saying one of the solos on Another Green World (I remember it as St. Elmo's Fire?) was created by manually piecing together tape snippets of individual notes. He shared an amusing anecdote: said the solo was impossible for any guitarist to play, yet he had heard from someone who claimed to have nearly mastered it - he chuckled at the amount of effort that must have taken.
Internet searches come up empty, and in fact the St. Elmo's solo is noted for being done in one inspired "lighting in a bottle" take..
Does this ring a bell with anyone? I don't think I imagined this - but... ?
