All of these bands have agreed to allow people to tape and distribute their concerts for free. This is most popular in the jam band community, but you’ll find a plethora of other bands that allow it as well.
I see! May I suggest adding this awesome japanese band from the 60's? Les Rallizes Dénudés - not sure about the legal status, but there's a lot of live material and afaik the band incentivized bootlegs, perhaps inspired by the Dead!
