A previously unreleased 'Doctor Who' score, mastered from the original tapes. Includes additional electronic tracks from Don Harper's catalogue and music featured in George Romero's 'Dawn Of The Dead'. This collection of horror-electronics, supernatural soundscapes and sinister library muzak is based on a previously unreleased score for the 1968 'Doctor Who' series 'The Invasion' (a dark otherworldly sci-fi jazz suite). 'Cold Worlds' is also a focus on the electronic music of Don Harper, a largely unsung composer. Like many Australian film composers (Ron Grainer, Dudley Simpson, Don Banks) Don Harper relocated to the UK during the 1960s and subsequently found employment with the BBC and other British film and library companies.
