The score from The Empire Strikes Back composed by John Williams. Between Star Wars and The Empire Strikes Back, Williams had also worked with the London Symphony Orchestra for the scores to the films The Fury, Superman and Dracula. The score earned another Academy Award nomination for Williams. Again, the score was orchestrated by Herbert W. Spencer and Angela Morley, recorded by engineer Eric Tomlinson and edited by Kenneth Wannberg with supervision by Lionel Newman. John Williams himself took over duties as record producer from Star Wars creator George Lucas.
The soundtrack was first released in the United States as a 75-minute double LP five days before the film's premiere but the first Compact Disc release ran only half the length of the 2-LP set. Re-recordings of the score even included music that was not on the original CD soundtrack. A remastered version of the soundtrack was released by Walt Disney Records on May 4, 2018.
