Charity supergroup

A charity supergroup is a music group comprising famous musicians or other celebrities which is formed to raise funds or awareness for charities or causes. The supergroup is usually together only for a single album, performance, or single.

The concept dates to at least 1971, when George Harrison and Ravi Shankar organized The Concert for Bangladesh, and a subsequent album and film, to support UNICEF relief efforts in that country. In the 1980s, forming a one-off supergroup to record a charity single became a popular way to promote a cause; notable examples include Band Aid's "Do They Know It's Christmas?" in 1984 and USA for Africa's "We Are the World" in 1985, both recorded to support famine relief in Ethiopia.
