I did this 80' CDR myself, and in fact it was taken from 3 other RoIOs: "Starclub Phyco", "Stone Rust" and "The Live Pink Floyd". For Copenhagen 1967, I took "Stone Rust" because the sound quality is slightly better than on "Starclub Phyco" (less hiss), but I had to use "Starclub Phyco" because this one contains the talking and instruments tuning between songs (missing on "Stone Rust"). I corrected the speed and remastered the whole thing (basically I centered the recording because the source is mono, and I normalized it). For Rotterdam 1967, I just took the best recording I know ("The Live Pink Floyd") and slightly remastered it (corrected speed, normalized and centered). Don't expect an excellent sound quality, but I think this is the best quality available for the moment. Marc-Olivier
