I'm of the opinion that Pink Floyd is one of the great bands of all time, one of the top practitioners of British blues-based art-rock. I'm a little surprised at the backlash, perhaps they're a bit too popular to be considered top flight fine art? But I consider Dark Side of the Moon and Wish You Were Here to be 2 of the best rock albums ever. Then there's Meddle, Animals, and The Wall, very very fine albums. Then there's the rest, I'm really not a fan of the Syd Barrett years, but with the arrival of David Gilmour and his incomparably tasty guitar playing and fine ethereal voice, the band was elevated to a juggernaut.
Their albums set a high water mark in terms of production and sound quality. Their use as demo discs has no doubt led to overplaying and more backlash, but I pay that no mind. They also rip pretty hard as a live act, pity they didn't record all those great shows in the '70s, we're left with mostly just audience recordings. But I dig Wembley '74 (I believe the whole show can be pieced together from the Immersion boxed set, and 1967-1972 Continu/ation). And the live album of The Wall, Is There Anybody Out There?, is outstanding.
