David Jackman (musician)

David Jackman is a British musician and visual artist known for his extensive catalogue of drone works, primarily as the principal and often sole member of the music project Organum. Jackman's musical journey began as a member of Cornelius Cardew's Scratch Orchestra where he was an active participant from 1969 to 1972. He highly valued his experience in the ensemble, writing in 1994: "I joined the orchestra in 1969 and soon found myself thrown into an energetic environment where to my surprise my musical ideas, however tentative, would be taken seriously and would actually get realised". In 1979, he started releasing limited-edition cassette singles, aligning with the underground cassette culture of the time.
