Outside of his iconic work in pop songcraft, Eno defined ambient music by contributing several quiet, powerful touchstones to the genre in the '70s. Music for Airports transforms your environment as various melodies slip in and out of perception—a trick also used by classical composers. As a producer, he brought this approach to his work with Bowie; their collaborative ambient tracks reflect Eno's laidback yet intricately textured approach. Eno's catalogue is vast in impact and variation, with some of his melodies swaying gorgeously while others embrace harsh electronic tones and samples.
