recording features shorter, high-register keyboard lines which syncopate with the music's modal base. The B-side of the original LP is titled "Poppy Nogood and the Phantom Band." It is a saxophone-based drone piece featuring tape loops and jump cuts. The piece is a version of the performances given at Riley's "All-Night Flight" concerts in the late 1960s. It employs overdubbing, with Riley again playing all instruments, (with saxophone inspired by the playing of John Coltrane). Riley used a time lag accumulator, consisting of two tape machines, looped audio tape, and a patch cord. The titular Phantom Band refers to Riley's tape delay accompaniment. A note on the album explains that "The spatially separated mirror images were adapted for studio recording by Glen Kolotkin and resemble the sound Terry gets in his all-night concerts." Release and legacy The original LP jacket includes a idealistic poem on the back cover, written by Riley, which depicts a world in which the Pentagon is "turned on its side and painted purple, yellow & green within a plainly psychedelic environment" and "the concept of work was forgotten." The album received a favorable review in Rolling Stone. Writing for The Village Voice, critic Robert Christgau opined positively that the "title side of this has to be a fair approximation of the music of the spheres." The album inspired Mike Oldfield's Tubular Bells and Pete Townshend's organ parts on The Who's "Won't Get Fooled Again" and "Baba O'Riley," the latter named in tribute to Riley and to Meher Baba. It has also inspired progressive, jazz fusion band Soft Machine's instrumental piece "Out bloody rageous". A Rainbow in Curved Air has also had a significant impact on the developments of minimalism, ambient music, jazz fusion, new-age music, progressive rock, and subsequent electronic music. It foreshadows the later overdubbed instrumental works composed by Steve Reich. The 1970s progressive rock band Curved Air named itself after this album. The album's title track is also featured in the video game Grand Theft Auto IV on the in-game radio station "The Journey." Some of the music on this album was used as the background accompaniment of The Guide in the original BBC Radio 4 series of The Hitchhiker's Guide to the Galaxy by Douglas Adams. Was sampled/copied as the sound effects for the 1980 arcade game Moon Cresta. Other appearances In 2009 the track "Poppy Nogood and the Phantom Band" featured in
