I've found a large collection of Pink Floyd recordings on Bandcamp. They sound genuine, and before purchasing I was wondering whether there's any comment on their authenticity.
Some of the albums I'm interested in;
The Wall Live 1980 https://chrismontgomery1.bandcamp.com/album/the-wall-live-1980
Zabriskie Sessions https://chrismontgomery1.bandcamp.com/album/zabriskie-sessions
Also whom is Chris Montgomery and how is he associated to Pink Floyd?
