This shirt is often referred to a Music for Rhinos shirt. There is another one that has “Music for Rhinos” written on it. But what is Music for Rhinos even? It’s hard to find evidence online, is everyone selling this shirt just copying from each other and nobody really knows?

Apparently, there is a book called “Music for Rhinos: The making of Pearl Jam”. I couldn’t find any additional infos, so please help a brother out and bless me with your knowledge.
