i think the live from pompeii has two editions..one with just the concert, and another with some animations that seem like CEV's, it is called the "director's cut".
i, as a musician, am very sad to see other musicians dislike pink floyd just because they were not after virtuosism. i find that this band created beautiful ambiences, and were more than the virtuosos that play in bands that sound all the same. it is nice to say that a band has a pink floyd sound! that sure means that they were original, and not like the other "play-as-many-notes-as-you-can-in-the-least-amount-of-time" bands. there are few bands like pink floyd (the originality part) nowadays, but i can find two of them: tool and radiohead. not sure if you agree with me, but that's what i think.
anyway, watch the director's cut, because you'll find it so much more amusing!
