In the summer of 1969 Michelangelo Antonioni completed the filming of his visionary and prophetic view of America and our society. All that was left was to complete the movie with a good soundtrack. Antonioni was interested in everything that was new and trendy among young people. Don Hall was on the air during his nocturnal DJ program on KPPC FM Pasadena when he was contacted personally by Antonioni at the end of the summer of 1969. Antonioni really liked Don and invited him to have some screenings of the movie. After that Don provided a list of songs he felt would work, most coming from his program. Antonioni asked MGM to hire Don as Music Advisor for the soundtrack and came back to Roma (Don still has a letter from Antonioni, sent from Rome with the list of the songs he’d like to be in the movie, all songs for the radio-desert sequences). Still they had to find how to score all the main sequences: Beginning, Violent, Take Off, Love and Explosions sequences (and eventually more). Antonioni wanted original music for those sequences. Many artists and bands were contacted to write original music for the movie, but none of them was asked to write the whole soundtrack of the movie.
Pink Floyd produced a large quantity of music, especially for the Love Scene but Antonioni was not satisfied and the sessions ran longer than planned. In the end Pink Floyd went back to London with some songs to finish. Out of all the entire production of songs, including themes and variations, Antonioni ended up using only three songs. He kept on searching for “something better” till the last days before the premiere of the movie. In London Pink Floyd completed their final versions of eight songs with the intent of them being their eventual album for the Zabriskie Point soundtrack.
