Alexander Noice is a Los Angeles–based composer, guitarist, producer, and bandleader whose work inhabits the space between contemporary composition, improvisation, electronic music, and art rock. Whether writing for chamber ensembles, building electroacoustic works in the studio, or leading his ensemble NOICE, his music is driven by an interest in intricate structures that remain visceral, emotionally direct, and alive in performance.

As both a composer and performer, Noice has appeared throughout the United States, Europe, Australia, Japan, and South America, collaborating with artists including Wadada Leo Smith, Famoudou Don Moye, Vinnie Colaiuta, Tim Lefebvre, Vinny Golia, David Binney, Wild Up, Dorian Wood, and Daniel Rosenboom. He has performed at many notable venues including Walt Disney Concert Hall, REDCAT, Blue Note Tokyo, Roulette, the Hammer Museum, and the Troubadour, as well as festivals such as the Monterey Jazz Festival, MATA Festival, Angel City Jazz Festival, Desert Daze, Sónar Tokyo, and Green Umbrella at the Los Angeles Philharmonic. He has also been an artist-in-residence at Ucross, Kimmel Harding Nelson Center for the Arts, and Loghaven.

After emerging as one of Los Angeles' distinctive guitar voices, Noice expanded his practice into composition across a wide range of media, creating works for chamber ensembles, improvising ensembles, film, animation, and multimedia installations. His 2016 solo electronic album Music Made With Voices transformed a single sung pitch from eight different voices into an entire sonic world, revealing an early fascination with finding expansive musical possibilities within tightly defined systems.

Noice founded the six-piece ensemble NOICE in 2014, developing a group language that dissolves the boundaries between post-minimalism, jazz, electronic music, and experimental rock. Described as "acrobatic in its execution and cinematic in scope," the ensemble has become known for performances that blur the line between precision and spontaneity. Their critically acclaimed 2019 debut established the group's singular aesthetic, and a new album is forthcoming on Innova Recordings, the label of the American Composers Forum.

Recent projects include Autotelic, a commission for the Grammy Award-winning percussion ensemble Third Coast Percussion that premiered in 2025, and Perpetually and Forever, an electroacoustic album released on Orenda Records in 2026. Writing in PopMatters, one critic called the album "a wild ride... one that has something for every adventurous listener."
