The Barrons finally released their soundtrack in 1976 as an LP album for the film 's 20th anniversary ; it was on their very own Planet Records label ( later changed to Small Planet Records and distributed by GNP Crescendo Records ) . The LP was premiered at MidAmeriCon , the 34th World Science Fiction Convention , held in Kansas City , MO over the 1976 Labor Day weekend , as part of a 20th Anniversary celebration of '' Forbidden Planet '' held at that Worldcon ; the Barrons were there promoting their album 's first release , signing all the copies sold at the convention . They also introduced the first of three packed-house screenings that showed an MGM 35 mm fine grain vault print in original CinemaScope and stereophonic sound . A decade later , in 1986 , their soundtrack was released on a music CD for the film 's 30th Anniversary , with a six-page color booklet containing images from '' Forbidden Planet '' , plus liner notes from the composers , Bebe and Louis Barron , and Bill Malone
