Though not the earliest entry in the genre (which Eno makes no claim to have invented), ‘Ambient 1 (Music For Airports)’ was the first album ever to be explicitly labelled ‘ambient music’. Eno had previously created similarly quiet, unobtrusive music on albums ‘Evening Star’, ‘Discreet Music’, and Harold Budd's ‘The Pavilion of Dreams’ (which he produced), but this was the first album to give it precedence as a cohesive concept.
