This list doesn't include the unreleased albums that can still be in heard in full today. That means favorites like 50 Cent's Power Of A Dollar, which was heavily bootlegged around its early 2000 release, or the Beach Boys' Smile, which remained unavailable until it was remastered and released in 2004.
The album, however, was incomplete, as tenor saxophonist Paul Gonsalves wasn't fully miked, and it was bolstered by in-studio recordings. In 1996, a complete recording of the Newport set, made for an overseas Voice of America broadcast, was uncovered and restored, as part of a 1999 remastered CD release. 2b1af7f3a8
