Could the Grateful Dead have been using Creative Commons principles decades ahead of time? This Matthew Helmke article from opensource.com makes the connection.
Although many bands at the time allowed fans to record shows, the Grateful Dead took the idea a step further. Fans who purchased “tapers’ tickets” were given access to a special area located near the soundboard. The band even encouraged tapers to share their recordings, as long as no profits were made on the sale of their tapes.
Creative Commons took inspiration from the Free Software Foundation (FSF) and its GNU General Public License (GNU GPL). Their goal is to find ways to use private rights for public good and to set creative works free, but only for certain uses.
Creative Commons has come up with a set of licenses that keep the power over creative works in the hands of creators while also freeing the content to be used in ways that modern copyright law forbids, much like the Grateful Dead did with their creative ticketing and taping permissions.
In the end, we get a legal means of fulfilling the freedom that the Grateful Dead allowed its fans, without gray areas that could lead to problems such as those that the Internet Archive had with the soundboard recordings of Grateful Dead concerts. This legal murkiness blocked access to those recordings for some time, although they are now available.
So the Grateful Dead has maintained a long and successful career using principles of openness and freedom that didn’t get formalized until much later in the Creative Commons licenses. I think it’s safe to say that the band would have used a CC license if they had been available at the time.
