I am a big fan of live audience recordings and was made aware of this gem that showed up a month or so ago on Youtube.
The concert story:
The show happened 2 weeks after the release of Dark Side of the Moon so the entire second set was basically brand new to most Floyd fans, there is no world currently where a rock fan doesn't know this material. They decided to use a stage lift in RCMH and it delayed the start of the show which was scheduled for St. Patrick's Day in NYC! Show didn't start until 3/18 @ 1:00AM. This would be the last tour Pink Floyd did where they primarily were in Theaters and would also be the last of many concert staples that were originally released previously to DSOM were performed live by the core 4 members.
**Mastering Recording Notes:**
This is a matrix recording of two different audience resources:
Recorder 1 is very ambient-sounding; the taper must have been sitting far back from the stage. However, it compliments the other recorders very well, being that the other two are closer to the stage - and are more direct-sounding. It was pretty muffled at first, so I gave it a boost in the highs. Recorder 2 was plagued with multiple issues, such as channel dropouts and wow and flutter issues. Unfortunately, when the dropouts occur, there is almost always no information on the other channel, making it impossible to repair the stereo image. In this case, it folds down to mono - only using the intact channel. This recorder also suffers from excessive skipping/flutter. I tried fixing this, but to no avail; it seems impossible to fix. The quality of recorder 2 also degrades by quite a bit during Any Colour You Like, so I felt it was best to leave it out completely. I’d be more than happy to make a revised version if better sources end up surfacing.
Pink Floyd themselves have confirmed that they have a multi-tracked SBD for this show in their archives, hopefully it will be released one day.
