10 000 Hz Legend

10 000 Hz Legend is the second studio album by French electronic music duo Air, released in France on 28 May 2001 by Virgin Records and in the United States on 29 May 2001 by Astralwerks. On this album, tracks are longer and more electronic-oriented than on their previous records. These experimentations find the duo expanding their capacities and working with other artists including Beck and suGar Yoshinaga of Buffalo Daughter.

The album artwork was produced by Ito Morabito. It features Monument Valley, located on the Arizona–Utah border.

Critical reception
10 000 Hz Legend received generally less favourable reviews from critics than had their previous albums. Most reviewers focused on the group's departure from the sound of 1998's Moon Safari, although the soundtrack album The Virgin Suicides (2000) had a similar mood and sound. Q listed 10 000 Hz Legend as one of the 50 best albums of 2001.

The American music website Stereogum takes its name from the lyrics of the song "Radio #1".
