Absolutely Free is the second album by The Mothers of Invention, led by Frank Zappa. Absolutely Free is, again, a display of complex musical composition with political and social satire. The band had been augmented since Freak Out! by the addition of saxophone player Bunk Gardner, keyboardist Don Preston, guitarist Jim Fielder and drummer Billy Mundi. Fielder quit the group before the album was released and his name was removed from the album credits.
This album's emphasis is on interconnected movements, as each side of the original vinyl LP comprises a mini-suite. It also features one of the most famous songs of Zappa's early career, "Brown Shoes Don't Make It," a track which has been described as a "condensed two-hour musical".
In the book Necessity Is..., former Mothers of Invention band member Ray Collins said that Absolutely Free is probably his favorite of the classic Mothers albums.
