Sly & the Family Stone
One of the first racially integrated bands, San Francisco's Sly & the Family Stone combined soul, funk, and psychedelia in its music. They played eight songs at Woodstock, including "Dance to the Music," "Stand!," "Everyday People," and "I Want to Take You Higher." Woodstock made the band popular, but Sly Stone's drug use brought them down.
When the band was inducted into the Rock and Roll Hall of Fame in 1993, many of the founding members performed, but Sly, in a surprise appearance, accepted his award and disappeared. Then, during a Sly & the Family Stone tribute at the 2006 Grammy Awards, Sly joined the band in the middle of "I Want to Take You Higher," but left the stage before the song ended.
