McDonald and Giles is an album of music released by British musicians Ian McDonald and Michael Giles in 1971. The album was first issued on Island Records (ILPS 9126) in the UK and in the US as Cotillion Records (SD 9042), a division of Atlantic Records. The album was recorded at Island Studios between May and July 1970. Although McDonald and Giles remains popular among King Crimson fans, its commercial success was limited. The duo did not record a second album.
Ian McDonald and Michael Giles were members of the original King Crimson line-up, and were featured performers on the band's debut album, In the Court of the Crimson King (1969). Both left the group at the end of its first North American tour in 1969, although Giles appeared on the second King Crimson album, In the Wake of Poseidon (1970), as a session musician. Two other King Crimson members also worked on McDonald and Giles: Peter Giles and Peter Sinfield.
The music on McDonald and Giles contains many of the pastoral and musically complex elements of King Crimson, while generally avoiding that band's darker tendencies. The song "Flight of the Ibis" has a similar melody and rhythm to King Crimson's "Cadence and Cascade", with different lyrics. The album contains a guest appearance by Steve Winwood, playing organ and piano on "Turnham Green". Winwood's group Traffic were working on John Barleycorn Must Die at Island Studios at the same time.
