First held in 2000 by a group of organizers in Olympia, WA, Ladyfest has grown into an international event that celebrates the "artistic, organizational, and political work" of women, and combats inequality by fostering a positive community. This year's Philly celebration will feature more than 20 female-fronted bands, as well as numerous girl-only workshops on how to change a bike tire, build a webpage, defend yourself, and more.
