At the time when a computer with the processing power of a pocket calculator was still the size of a caravan, and electronic music hardly counted as music – let alone art! – composers such as Suzanne Ciani, Pauline Oliveros, Daphne Oram and Laurie Spiegel embarked on creating the sounds of the future with tape reels, scissors and sticky tape as their instruments. They were all women, and when electronic music was finally recognised, they were almost forgotten. Lisa Rovner rectifies this imbalance in ‘Sisters with Transistors’. With style and substance, and through a gold mine of rare clips of buzzing synthesisers and wild artistic creativity, the story of the female pioneers is rolled out for the first time. The energy, curiosity and enthusiasm for the medium is not just present in the sounds and the music, but in every image of Rovner’s stylish and uncompromising film about the liberating potential of art. Laurie Anderson has lent her voice to the narration, which ties it all together.
