Loads of bands organize/trade/sell recordings of each show. It's smart and effective to prevent commercial piracy, mastered early on by the Dead community, but also Phish, The Who, Bruce, and U2 have done it.

The Stones "Vault" series has been an effective way to add copyright protection to their own unreleased master recordings, which ended up stolen from them at some point, by employees and vendors of the band.

When a band owns great masters, (as the Stones do now for every show that has used video projection - so almost every single concert since at least 1989) they simply have to make them available for sale to add a copyright protection. And then they can legally stop licensed online retailers from selling them.

When you or I tape a show, we own that recording, The Stones have no rights to use it commercially. However, the performance (if it's a ticketed event on private property) has it's own copyright, so we have no right to sell it either.
