A Rainbow in Curved Air

This isn’t ambient music — it’s a blueprint for how to build time out of tape, touch, and repetition.

A Rainbow in Curved Air is a solo studio construction: keyboard and percussion overdubs on the A-side, saxophone drone and tape manipulation on the B-side. Made in 1968 on one of CBS’s first eight-track recorders. It established repetition, delay, and modal layering as core tools for electronic composition — not as texture, but as architecture.

    Saxophone as Drone, Tape as Conductor

    ‘Poppy Nogood’ is saxophone-as-drone, constructed from tape loops and delay — rooted in Riley’s all-night performances.

The written brief1 min read

What the record is and where it came from

An overdubbed electronic album recorded in 1968 and released in 1969. Riley performed every instrument using an early CBS eight-track recorder. It grew from his all-night improvisatory concerts and fuses jazz phrasing with Hindustani classical modality.

How it sounds, and how it was made

The title track layers Riley’s overdubbed electric organ, two electric harpsichords (Baldwin and RMI Rock-Si-Chord), dumbec, and tambourine. It opens with placid chords, then introduces right-hand keyboard lines that flutter and pirouette over pulsing rhythms. The calmer second half uses shorter, high-register keyboard lines syncopating with a modal base. ‘Poppy Nogood’ is saxophone-based, built from tape loops, edits, and delay — all performed by Riley.

What lands

The title track’s rhythmic pulse and keyboard interplay land with physical clarity. The B-side’s saxophone drone lands as immersive texture — sustained, breathing, slightly unstable.

What does not

It does not use synthesizers. It does not feature orchestration, vocals, or external collaborators. It does not rely on harmonic progression or verse-chorus form.

The ideas inside it

Improvisation as architecture. Modal repetition as propulsion. Tape delay and overdubbing not as effects but as compositional logic — where time folds, layers accumulate, and drone becomes narrative.

Who should hear it, and who should not

Producers working with tape, modular systems, or loop-based composition should hear it. Listeners who value rhythm as structure — not just groove — should hear it. Those expecting melodic development or conventional songwriting should not.

Is it worth your time

Yes. It is one of the earliest professional eight-track recordings and a direct conduit from Hindustani raga and jazz improvisation into electronic music’s structural vocabulary.

DrukqsAphex Twin · 2001Drukqs is a double album released in 2001 by Aphex Twin. It contains tracks dating back seven or eight years, though most were relatively new. James rushed its release after accidentally leaving an MP3 player with new tracks on a plane, aiming to preempt an internet leak.

Funkentelechy vs. the Placebo SyndromeParliament · 1977Funkentelechy vs. the Placebo Syndrome is Parliament’s sixth studio album, released November 28, 1977, on Casablanca Records. It is a loose concept album set within the P-Funk mythology warning of the 'Placebo Syndrome' — consumerism and disco music, which George Clinton viewed as a crass commercialized variant of funk. The album features layered vocal performances, synthesizer-heavy arrangements (especially on 'Flash Light'), and collaborative guitar work across multiple tracks. 'Flash Light' became an R&B number one single, built around a prominent Minimoog bass line played by Bernie Worrell. The original vinyl release included a 22″×33″ poster of Sir Nose D'Voidoffunk and an 8-page comic book explaining the concept — both illustrated by Overton Loyd. Vocalists include George Clinton, Ray Davis, Glenn Goins, Garry Shider, Debbie Wright, Jeanette Washington, Lynn Mabry, Dawn Silva, Cordell Mosson, and Mallia Franklin (though Franklin is not listed on the liner notes). Guitarists include Michael Hampton, Glenn Goins, Garry Shider, and Phelps Collins (on 'Flash Light'). 'Sir Nose d'Voidoffunk (Pay Attention – B3M)' quotes 'Baa, Baa, Black Sheep' and 'Three Blind Mice', with altered lyrics referring to drug use.

Midnight StarMidnight Star · 1988Midnight Star (1988) is a post-breakout album with no documented commercial performance, stylistic departure, or critical repositioning. It relies on the same R&B/funk/vocoder foundation established by No Parking on the Dance Floor (1983), but none of its tracks charted, none received significant airplay, and none are cited as defining the band’s identity.
