Ahead Of Their Time is a live album by Frank Zappa and The Mothers Of Invention. It was recorded at the Royal Festival Hall, London, England on 28 October 1968, and released in 1993 on CD by Rykodisc.

The first part of the set is a one-off performance of a musical play retrospectively entitled Progress?, and featuring members of the BBC Symphony Orchestra. Portions of this performance originally found their way onto the Weasels Ripped My Flesh album and the Honker Home Video release of Uncle Meat. Much of the humour and storyline of the play is lost to the casual listener due to primitive recording techniques and the visual nature of some of the performance, necessitating extensive liner notes by Zappa. The remainder of the set is "A fair - not outstanding - 1968 Mothers Of Invention rock concert performance" (Frank Zappa - Ahead Of Their Time liner notes).

Musicians

Frank Zappa, Ian Underwood, Bunk Gardner, Roy Estrada, Euclid James Motorhead Sherwood, Don Preston, Arthur Dyer Tripp III, Jimmy Carl Black, members of the BBC Symphony Orchestra.
