It's really up to the artists. Many are surprisingly cool with it, though there are a few notable exceptions (i.e. Prince). Sounds like the artist in this particlar case gave their blessing.

Many bands (like GD and Phish) specifically note in their rider that venues must allow and provide space for tapers to bring their rigs in.

A sibling comment in this thread pointed out my project Relisten[0], which now has over 4,000 bands who have given explicit permission for people to tape, record, and share their concerts non-commercially. We've been operating our FOSS platform for 12 years, and most of the audio is hosted by Archive.org. I can't tell you how many bands have begged us to add them to our platform.

Prince had intense business instincts, not just for becoming a vertically integrated multi-instrumental composer manager, bandleader and of course prodigious artist. Its rumored that to ruin the market demand for his bootleggers, Prince started his own sockpuppet bootleg label, that eventually released over four hundred CDs of content. Concerts, studio alternate cuts, and of course After-Shows. That label is curiously named Sabotage.

Whether the rumor is true or not, I can't confirm. What I can tell you is it's an amazing soundboard quality collection of his work product that I'm still not all the way through exploring after it briefly circulated among fans for a brief moment shortly after his death.

There was an episode of "What's Happening" when Rerun gets in trouble for bootlegging a Doobie Brothers concert, does anyone remember? It aired when I was a kid and now I somehow still feel guilty when I listen to bootlegs.

Well. Just wanted to say how much I appreciate Relisten. I listen almost every day.
