Mickey Hart is an American percussionist, musicologist, and author, best known as a member of the Grateful Dead, a seminal rock band that emerged in the 1960s. Born on September 11, 1943, Hart's primary genre is rock, but his work spans various styles, including world music and experimental music. Notable works include his collaborations with the Grateful Dead on albums like "American Beauty" (1970) and "Workingman's Dead" (1970), as well as his Grammy Award-winning solo projects such as "Planet Drum" (1991), which explores global rhythms and features musicians from diverse cultural backgrounds.

His interest in the intersection of music and consciousness is reflected in his writings, including "Drumming at the Edge of Magic" (1990).
