Band Aid was a British supergroup formed in 1984 by Bob Geldof and Midge Ure. Prominent for its philanthropic endeavors, the group amassed various leading British and Irish musicians to record the charity single "Do They Know It's Christmas?" to raise funds for famine relief in Ethiopia. Their signature sound was a fusion of pop, rock, and new wave, with multiple vocalists and instrumental layers. Despite its short-lived existence, Band Aid has left an indelible mark on music history, setting a precedent for subsequent music-based charity initiatives.
