A Rainbow in Curved Air is the third album by experimental music and classical minimalism pioneer Terry Riley. Through the use of overdubbing, the composer, a keyboard virtuoso, plays all the instruments on the title track: electric organ, electric harpsichord (Rock-Si-Chord), dumbec (or goblet drum), and tambourine. The work begins with a simple minimalist drone but quickly erupts in exciting rapid-fire figurations far removed from typical slowly evolving minimalist structures (as in Riley's own In C). The rest of the piece explores various layered keyboard and percussion textures.

The largely improvisational nature of the work, based on modal scales, owes much to jazz and Hindustani classical music. Some jazz musicians had explored overdubbing techniques before, notably Bill Evans, one of Riley's piano "heroes",[3] on his classic album Conversations with Myself from four years earlier, with its three piano tracks; but Riley uses a far wider range of instruments and colors.

Although continuous in form, A Rainbow in Curved Air can be seen as having three distinct sections or "movements," like a classical sonata or concerto. The first "fast" section gives way to a more contemplative "slow movement" at 6:39. Then, the final more rhythmic section begins at 11:41, dominated by the dumbec, which creates a parallel to how a tabla enters in the final section of a Hindustani raga. The work then ends abruptly.

The combination of the one-man-band overdubbing, electronic instruments, and improvisation made for a unique and influential recording, a defining psychedelic work of the 1960s, enhanced by its cover art and the peace poem that constitutes the liner notes.

The companion piece, which constituted the "B" side of the original album, is titled "Poppy Nogood and the Phantom Band." It also employs overdubbing, with Riley again playing all instruments, this time a soprano saxophone (inspired by the playing of John Coltrane)[4] and electric organ. In addition, Riley used a time lag accumulator, consisting of two tape machines, looped audio tape, and a patch cord (this is the "Phantom Band" of the title).[5] 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."
