This is essentially essential. Of all the King Crimson live albums, this one is at the top of the heap for me. Many people will argue that the seventies Crimson King was the best and/or most progressive lineup, and this album is surely an argument for that. There are really few, if any, flaws here. The playing is masterful, the interplay is top notch, and, perhaps above all, the music is exciting and relentless, constantly flowing with great ideas and moments that really speak the wonders of progressive rock. For all intents and purposes, consider this a five star rating without the actual five star rating. Extremely recommended.
