Tetraphonics: Lea Bertucci's Quadraphonic Cello

A live concert recording of Lea Bertucci’s Quadraphonic Cello, an instrument outfitted with a customized pickup designed specially for 4-channel sound. Noise rather than pitch dominates the aesthetic approach, with texture and timbre in the foreground. Interdisciplinary artist and avant-garde cellist MV Carbon performs the composition by Bertucci, with programming by Tommy Martinez.

This performance was part of the Clocktower's March 2016 Tetraphonics event presented in collaboration with Lea Bertucci at Pioneer Works where four artists explored quadraphonic sound and its mesmeric effects in performance alongside 4-channel video work.

An instrument, multichannel installation, and platform for audio-visual composition, the Quadraphonic Cello re-imagines a classical cello as a vehicle for surround sound. A customized pickup using piezo-electric component technology is attached directly to each of the four strings. When the cellist bows, plucks or taps, four discrete signals are produced and routed to a quadraphonic array of speakers. Developed through the Harvestworks New Works Fellowship, this instrument is a three dimensional musical apparatus tailored to multi-channel composition and the sculpting of acoustic space.

Lea Bertucci is an American sound artist, composer and performer whose work incorporates acoustic phenomena, biological resonance, multi-channel speaker arrays, electroacoustic feedback, extended instrumental/vocal technique, and tape collage. As an instrumentalist, she uses an idiosyncratic approach to the amplification of woodwind instruments, creating organic yet electrified sonic interventions.

MV Carbon is a New York City-based, interdisciplinary artist and composer. Her work is comprised of sound, installation, projection, and performance. Embracing a non-traditional approach to music, she plays cello, amplified objects, vocals and crafted instruments through circuits and electronics, analog synthesizers and oscillators.

Clocktower Exhibits & Events


The Clocktower Gallery was founded by the alternative spaces movement pioneer Alanna Heiss in 1972. After a hiatus as a gallery space (after the Sept. 11, 2001 events nearby), the Clocktower Gallery reinaugurated its exhibition programming in 2005 as part of MoMA/PS1 and, after 2008, under the auspices of the newly founded Art International Radio (now Clocktower Productions). Clocktower Exhibits is home to interviews with and performances by its exhibitions' participating artists and curators over these many years.

For more Clocktower history, listen to The Clocktower Oral History Project, in which such figures as Vito Acconci, Bill Beirne, Colette, Jeffrey Deitch, Mary Heilmann, Jene Highstein, Ann Magnuson, Richard Nonas and Joel Shapiro reflect upon their experiences with this unique New York space. Organized by artist Nancy Hwang for the Fall 2009 AVANT-GUIDE TO NYC: Discovering Absence exhibition at apexart. .
