I came across a 2 CD set called the Complete Hollywood Bowl Concerts. I don't remember any "official" release of these performances other than the abbreviated 1977 releases on LP and cassette.
Is this set official? Was there any digital overhauling to improve the sound? This set doesn't sound much better than original releases, but I figured with the advancement in engineering in leaps and bounds since the analog 70s, there could be some improvements made.
Anybody have any info on this?
