Certain moments in the history of rock music stand out as instances where multiple musicians came together to fight for a common cause. The Concert for Bangladesh. Live Aid. Farm Aid. Live 8.
A short piece in Time considers the legacy of Farm Aid, first held on September 22, 1985. While farmers still have needs, these concerts have helped raise awareness for a nearly forgotten piece of American life. This is also a good example of how celebrities, musicians in this case, have tried to make aid for farmers a social problem that is worthy of more attention.
I wonder how effective concerts like these are. I remember watching Live 8 mainly for some of the musicians I enjoy listening to and not so much for the issues about which the musical acts were trying to raise awareness.
