Ian MacCormick (3 October 1948 – 20 August 2003), who wrote under the pseudonym Ian MacDonald, was a British music critic and author, best known for his detailed history of The Beatles and The New Shostakovich, a controversial study of the Russian composer Dmitri Shostakovich.
He briefly attended King's College, Cambridge, at first studying English but soon transferring to Archaeology and Anthropology. He dropped out after a year. While at Cambridge, he was distantly acquainted with the singer/songwriter Nick Drake.
From 1972 to 1975 he was Assistant Editor of the NME. He began a songwriting collaboration as lyricist with Quiet Sun, which included his brother Bill MacCormick and future Roxy Music guitarist Phil Manzanera. This collaboration was resumed in the late 1970s, when MacDonald provided lyrics for the album Listen Now. Later, Brian Eno would help MacDonald produce Sub Rosa, an album of his own songs, and release it on Manzanera's record label.
