I'm still not sure why Obscured By Clouds even warranted a remix. It already had/has an excellent stereo mix.
Well I tried de emphasis on pompei using foobar according to this link How I manually apply de-emphasis to CDs that have pre-emphasis. : headphones I must say that it really improved listenability. Before it was unbearable. Great result and thanks for pointing into this direction. I always loved the recording and played the dvd countless times. However it needed a lossless release, finding it as it was in the box was such a disappointment. Now I can properly enjoy it!
I think they didn't know what else to fill the 1972 volume with. Maybe they should have just included Pompeii with the 1971 volume (which is just one cd now) and called it '1971-1972'.
