“A big part of the genius of the post-Syd-Barrett-pre-Dark-Side-of-the-Moon Pink Floyd is just how scattered, unformed, incomplete so much of it is – the various albums and soundtracks and loose pieces arriving more like strange and fabulous reports on an ongoing indefinable work in progress than anything remotely complete. Case in point, the numerous versions of Careful With That Axe Eugene floating around (at least one going by a different title altogether). If I had to choose only one though, it would be the live version found on side one of Ummagumma, simply because it scared the hell out of me the first time I heard it. Grade Seven sometime, a friend’s older brother having some good clean bloodcurdling fun with us on a dark winter’s night.” (Philip Random)
