Under the Influence — 21 Years of Flying Nun Records is a double album that includes tracks by various bands signed or related to the Flying Nun Records label. The album was planned as a celebration of the 21st anniversary of Flying Nun Records. Bands invited to be part of the album were asked to record one or two songs; if two songs, then one should be a cover of a Flying Nun song that influenced or inspired them and the other song should be a new and unreleased song of their own. These were all to be recorded on a single day at York Street Studio on 22 March 2002.
