"The world is flooded with Dead bootlegs, but some of them are superb"
Which was partly why the Dead's approach was so clever. Back in the day, *GOOD* bootlegs of any band were usually pricey compared to official recordings and, of course, the bands saw nothing of that money. By making bootlegs ubiquitous, the Dead greatly reduced that premium.
There is an interesting philosophical question here: were these recordings bootlegs? Given that their production had been officially facilitated by the band, and thereby tacitly approved, it could be argued that they're not bootlegs at all but "official" recordings. At the very least they are official unofficial recordings!
