35. 'Xtro' (Harry Bromley Davenport, 1983)
Director Harry Bromley Davenport once described his 1983 sci-fi shocker Xtro as "an extraordinary mess," an assessment that the film's many critics would probably view as immodestly generous. Far more coherent than the film itself is its soundtrack, which was also penned and recorded by Bromley Davenport. Whether motivated by budgetary constraints, an admiration for John Carpenter's soundtrack work or both, Bromley Davenport – a trained classical pianist – went the minimalist analog synth route, mixing haunting melodies with whirring electronic effects and woozy waltzes. Soundtrack collectors and synth freaks alike willingly fork over big bucks for copies of the original.
