Two Sides of the Moon is the only solo studio album by the English rock musician Keith Moon, drummer for the Who. It peaked at No. 155 on the Billboard 200. The album title was credited to Ringo Starr. Rather than using the album as a chance to showcase his drumming skill, Moon sang lead vocals on all tracks, and played drums only on three of the tracks, although he played percussion on "Don't Worry Baby". The album features contributions from Ringo Starr, Harry Nilsson, Joe Walsh of the Eagles, Jim Keltner, Bobby Keys, Klaus Voormann, John Sebastian, Flo & Eddie, Spencer Davis, Dick Dale, Suzi Quatro's sister Patti Quatro, Patti's bandmates from Fanny Jean Millington and Nickey Barclay, and future actor Miguel Ferrer.

Keith John Moon was an English musician who was the drummer for the rock band the Who. Regarded as one of the greatest drummers in the history of rock music, he was noted for his unique style of playing and his eccentric, often self-destructive behaviour.
