Absolutely Free is the second album by American rock band the Mothers of Invention, released on May 26, 1967, by Verve Records. Much like their 1966 debut Freak Out!, the album is a display of complex musical composition with political and social satire.

Donald Johnson Ellis was an American jazz trumpeter, drummer, composer, and bandleader. He is best known for his extensive musical experimentation, particularly in the area of time signatures. Later in his life he worked as a film composer, contributing a score to 1971's The French Connection and 1973's The Seven-Ups.
