Warren Greveson is an electronic composer, musician and producer based in Beaumaris, Wales, UK. He has written and produced music for TV programme makers BBC, ITV, Discovery and the Children’s Channel. As a founder member of the eclectic electronic jazz quartet Zyklus, he has appeared at iconic venues including London’s Royal Festival Hall, Purcell Room and Barbican Centre. Zyklus, which also comprised Neil Ardley, John L Walters and Ian Carr, deployed the Zyklus MPS - a hardware sequencer also used around the same time by White Noise and Vangelis - as the basis for compositions, along with Ian Carr's trumpet and Greveson's guitar.The quartet gave several live performances and later also worked as a trio. Its album release, VIRTUAL REALITIES fuses jazz with repetitive and minimalist music, a style at which the Zyklus sequencer excelled. In 2012, Greveson performed an early realisation of the VOYAGER compositions at the 2012 Beaumaris Arts Festival with – for the first time - an orchestra playing alongside performers using iPads. The work has also been performed several times in the USA. Greveson told the BBC: "The idea of fusing technology with classical instruments is not new, but as far as I know no-one else has produced a work such as this," he said. In 2013, Warren Greveson released SONGS FROM THE GRAND MASSIF with Colosseum drummer Jon Hiseman and violinist Billy Thompson. Warren is also a founding member of ‘looping’ experimental jazz/rock band DOLENNU which released its self-titled debut in 2017 with the resurrected Zyklus sequencer.
