Hendrix was before my time of concert days, but I did mange to score a few years ago the 3m two track that a few of his master tapes were mixed down to. It came out of electric lady land. One of there techs had brought it to a pro sound out door yard sale back in the 80's.
The old 3m still works mint and is still in use when the recoding is worthy of a real anolog mixdown.
I wonder what other albums were mixed on it.
