Keith John Moon (August 23, 1946 - September 7, 1978) was the drummer of the rock group The Who. He gained notoriety for his exuberant drumming style and his destructive lifestyle. Moon joined The Who in 1964, replacing Doug Sandom. He played on all albums from their debut, 1965's My Generation, to 1978's Who Are You, which was released two weeks before his death.
Moon is known for innovative, dramatic drumming, often eschewing basic back beats for a fluid, extremely busy technique focused on fast, cascading rolls across the toms and cymbal crashes. Moon was one of the first to play the drums as a lead instrument in an era when drums were supposed to only keep the back beat. He is widely regarded as one of the greatest and most distinctive rock drummers of all time.
