Selected Ambient Works Volume II

Selected Ambient Works Volume II (abbreviated as SAW II) is a studio album by the British electronic music artist and producer Aphex Twin. It was released on 7 March 1994 through Warp Records. Its title follows James's ambient techno debut Selected Ambient Works 85–92, but Volume II largely features purely ambient music. James was inspired by lucid dreaming and likened the album to "standing in a power station on acid." Most of the tracks on Selected Ambient Works Volume II were untitled and represented with abstract photographs and pie charts. Fan-named, unofficial titles are still widely used today.

The record entered the CIN's Dance Albums Chart at No. 1 and the Albums Chart at No. 11. The album had a polarised reception from critics upon release. Contemporary critical reviews focus on its largely beatless composition and the repetition throughout. Retrospective reviews of the album are positive, and have described its major role in the evolution of ambient music and electronica. In 2016, Pitchfork picked Selected Ambient Works Volume II as the second greatest ambient album of all time, after Brian Eno's Ambient 1: Music for Airports. A remastered and expanded reissue of the album was released in October 2024 with two bonus tracks.
