Anyone who has more than a passing interest in bootlegs and ROIO will be aware of the late Mike “The Mic” Millard. A LA based music fan whose surreptitious recordings of the concerts he attended were astonishing good, especially for the late 70s period when he was most active. https://en.wikipedia.org/wiki/Mike_Millard
Some of his previously uncirculated recordings have started to become available, and today has seen the release of his recording of David Bowie on the Isolar II tour at the LA Forum in 1978. It’s currently being seeded on dimeadozen, and will no doubt start to become available on various blogs/YouTube/trackers/etc. I’ve just downloaded it and am listening with some Dead Man’s Fingers rum; both are utterly stellar.
