I saw that tour - easily one of the best shows I’ve ever seen/heard.
Album wise, “Hissing of Summer Lawns” is vastly underrated.
My fav is “Hejira”.
I also have CDRs of “Court & Spark” and “Blue” burned direct from the raw master studio tapes from a mastering engineer friend - superb engineering on those albums.
One final thought.
Joni did 3 versions of “A Case of You” but....
The absolute best version of that song is Diana Krall’s solo performance “Live In Paris” - light years beyond Joni’s versions in musicality and emotion.

The CD version (a different night/performance) is even better!
