This is one of those King Crimson Collector's Club releases which happens not because the recording itself is particularly good - it isn't, it's a cassette bootleg, probably from an audience member, and it sounds like one - but because of the historical importance of the show itself, with this being the final stop on King Crimson's 1974 US tour. After this, David Cross would be out, the sessions for Red would commence, and the original 1969-1974 run of King Crimson would be brought to an end.
The thing is, if you're enough of a Crimson fan that hearing this gig is that important to you, despite the very evident audio problems here, then you're probably going to want to get the Road to Red boxed set anyway, which includes this concert and a bunch of others of vastly superior audio quality.
