The festival that put women first debuts on July 5, 1997. Formed by Sarah McClachlan, the festival donated over $10M to charity over its run from 1997-99 and in 2010. (It also introduced me to the then Dixie Chicks on two nights — Milwaukee and Minneapolis — in 1999.)
McClachlan brought Lilith Fair to a close in 2011 citing changing musical tastes and changing demographics. I think she was premature.
