Blume presents two pieces composed in 1970 by the American pianist and composer David Tudor (1926-1996), one of electronic music's most important pioneers, for the Pepsi-Cola Pavilion, a unique artist-designed and programmed space for Expo '70 in Osaka, Japan, created by Experiments in Art and Technology (E.A.T.). Pepsibird and Anima Pepsi deploy electronic technology as a means to experience sound in ways that are anything but matter of fact, rendering liberated environments within and through which one might democratically express and commune. Viewed through the lens of what was, is, and might have been, they offer the tools for time travel: an unmediated encounter with radical, optimistic ideas that gave way to the complex cultural landscape of our time.
Initially trained on organ and then piano, Tudor emerged as a leading figure within New York's musical vanguard after his groundbreaking 1950 performance of Stefan Wolpe's Battle Piece and the American premiere of Pierre Boulez's Second Sonata. Within less than a year he had joined the Merce Cunningham Dance Company as its accompanist, a role he kept until his death, and began one of his most lasting creative relationships with John Cage, who would state that his entire output between 1951 and the end of the 1960s was written with Tudor in mind. Christian Wolff, Earle Brown, Morton Feldman, Sylvano Bussotti, Mauricio Kagel, and Karlheinz Stockhausen all wrote works for him during the 1950s and '60s. Through indeterminacy and chance-based methods, Tudor was noted for radically intervening with the works he played, often making them entirely his own, and it was this same singularity of vision that led him to gradually abandon the piano in favor of electronic process, through which he began working as a composer in his own right.
His engagement with electronics dates to the early 1950s and Cage's Project for Music for Magnetic Tape. By the following decade the pair had moved to live electronics, with Tudor rendering works like Cartridge Music and Variations II through contact microphones and complex systems of feedback and amplification. Before modular synthesizers existed, he designed and built his own electronics, often with engineers from Bell Laboratories, producing dozens of unique instruments and processing tools that helped lay the groundwork for the technological needs embraced by most electronic musicians ever since. A clear marker of his emergence as a composer came in 1966 with 9 Evenings: Theatre and Engineering, where he premiered Bandoneon! (a combine), turning the cavernous performance space into a feedback instrument and a total environment. The event led directly to the founding of E.A.T. the following year by the engineers Billy Klüver and Fred Waldhauer, alongside Robert Rauschenberg and Robert Whitman.
Among the most ambitious of E.A.T.'s projects was the Pepsi-Cola Pavilion, for which Tudor composed four pieces between March and April 1970: Pepsibird, Anima Pepsi, Pepscillator, and Microphone. Together with Forrest "Frosty" Myers, Robert Whitman, the sculptor and filmmaker Robert Breer, and the architect John Pearce, he was tasked with the design and function of the building: a 120-foot diameter steel and polyvinyl dome, shrouded in mist and fog and lit in the evenings by a square of intense blue-white xenon light. Tudor worked with Gordon Mumma and Fred Waldhauer on a unique sound system capable of processing and variable distribution through 37 speakers, controlled both by automated means and by the performer, and with Lowell Cross on a sound-activated laser deflection system inside the pavilion's mirrored performance hall.
Both pieces are an advanced form of musique concrète: libraries of tape recordings, live mixed and processed through the pavilion's sound console and distributed through 8 channels of stationary and rotating patterns designated by Tudor's instructions (small circle, great circle, large rhomboid, spiral, small triangles, small ovals). Pepsibird is focused upon a physical interiority, its source tapes being recordings of the brain wave activity of humans and animals: cat's eye, nerve firing, bats, EKG, alpha waves, a modified nightjar. Recorded in situ in 1970 and mixed down to stereo, it retains a striking sense of the space and ambience that Tudor achieved in performance. For more than eighteen minutes he merges subtle textures and pulses, at times resembling birdsong, within a blanket of vast, resonant ambience of subaquatic density, foreshadowing the relationship to the natural world of later works like Rainforest IV (1973).
Anima Pepsi is centered on the exterior: field recordings that Tudor made of animal and insect sounds (mosquitoes in a jar, a fly on flypaper, a wasp chewing, a beetle walking) and a mix of human and animal sounds that he called the "funny tape". Where Pepsibird deploys interior sounds in ways that allude to the natural world, Anima Pepsi pushes the sounds of nature and humanity toward the otherworldly through the clear presence of electronic sounds and processing, moulding detailed, pointillistic patterns of abstract sonority into gauzy blankets of ambience and space.
The collaboration did not last: less than a month after the opening, Pepsi withdrew its support, fired E.A.T., and disregarded Tudor's tapes, which according to accounts had to be smuggled out by staff, playing its own soundtrack in the pavilion for the rest of the Expo. Heard today, Pepsibird and Anima Pepsi anticipate many territories of later electroacoustic practice, from field recording to live processing, while the terms on which they were made, radically unpredictable, indeterminate, and experimental to the core, reconfigure what we've come to expect from electronic process, making one wonder if the past was ahead. Issued by Blume in a highly limited vinyl edition of 300 copies on red vinyl, with a 20-page LP-size booklet containing You Nakai's essay and newly commissioned liner notes by Bradford Bailey.
