I can see why fans of the 1980s incarnation of King Crimson would be interested in this release, since it's the live debut of that lineup - so early in their run that they were still calling themselves "Discipline". Already the material which would form the album is mostly in place - all the songs we know are present in early form here, plus Red.
The problem is that this is an audience bootleg of the show, and it sounds like one. To me, the music of the 1980s King Crimson is particularly badly served by lo-fi, poor quality recordings like this. In addition, if you're interested enough in the 1980s King Crimson that you badly want this, you may as well just get the On (and Off) the Road boxed set, which includes this as a bonus disc plus a bunch of other live shows in far better quality from the Fripp-Levin-Bruford-Belew era.
