Warthur
As much as I enjoy some of the live material from the Islands-era King Crimson lineup that Discipline Global Mobile has made available over the years (with the Sailors' Tales boxed set compiling more of these releases than you will ever really need at an astonishingly reasonable price compared to if you bought them separately), there's some live recordings of theirs where the sound quality simply is too poor to make it worthwhile. This Denver, Colorado gig was recorded to cassette from the soundboard and the nicest thing I can say about it is that it sounds a bit better than Earthbound - but there's other live recordings from the same tour which sound better than this.
In particular, the Summit Studios radio session recorded prior to this gig has much the same energy, but benefits enormously from the multi-track recording's far superior sound quality. Don't bother with this one unless you got it in the Sailors' Tales box - and even then, I'm willing to bet it'll be one of the shows you don't listen to so often.
