'The Last Wave' (known as 'Black Rain' in the US) was the final chapter in a trilogy of films scripted and directed by the leading auteur of the Australian New Wave, Peter Weir. With no LP issued after the film's premiere in 1977, and together with the mystery surrounding the true identity of its enigmatic composer Charles Wain, the score is a largely unheard recording of pioneering experimental film electronics, easily comparable to the music that Klaus Schulze and Tangerine Dream were composing for Australian films during the same period, or the electronic soundtracks of John Carpenter.
