Close Encounters of the Third Kind is Steven Spielberg's, now classic, exhilarating 1977 science fiction film. The masterful score was composed, conducted and produced by John Williams. The soundtrack is a mixture of eerie suspense and tremendous emotive bombast, complete with hair-raising moments and the great big playful musical conversation between the mothership and the humans. Williams' "five-tone" motif for Close Encounters has become ingrained in popular culture (the five tones are used by scientists to communicate with the visiting spaceship as a mathematical language as well as being incorporated into the film's signature theme). The album was a critical and commercial success, peaking at #17 on the US Billboard album chart and reaching #40 in the UK. John Williams won two Grammy Awards for his score (Best Original Film Score and Best Instrumental Composition). A disco version of the five-note motif, though not part of the original score, is included on the disc as a bonus track making this CD an essential acquisition for collectors and movie and music fans.
