A Gathering of the Tribes was a two-day music and culture festival organized by Ian Astbury and promoter Bill Graham, held in California in October 1990. It is considered the precursor to the Lollapalooza touring festivals of the 1990s, an opinion shared by Astbury himself. The festival was held at the Shoreline Amphitheatre in Mountain View on October 6 and the Pacific Amphitheatre in Costa Mesa on October 7. The event was intended to raise money for and awareness of Native-American-related causes. A performance by the American Indian Dance Theatre preceded the festival each day. The concert grounds also hosted tents for Act Up, Amnesty International, Greenpeace, Rock the Vote, and local animal rights organizations.
