Beneath the Planet of the Apes [SEP] Music
The original "Apes" composer, Jerry Goldsmith, was invited to write the score for the sequel, but Schaffner was using Goldsmith for "Patton". Leonard Rosenman was hired to compose the score. Rosenman tried to blend Goldsmith's distinctive score with his own style, showcased in productions such as "Fantastic Voyage". An official soundtrack LP was issued on the Amos Records label soon after the film's debut in 1970. For the LP, Rosenman was asked to rearrange his score for a smaller orchestra, adding contemporary elements such as electric guitar and rock percussion. These re-recorded pieces were interspersed with dialogue taken from the film.
