The works of composer and sound artist Kali Malone implement specific tuning systems in minimalist structures for pipe organ, choir, chamber music ensembles, and electroacoustic formats. Malone’s compositions are rich with harmonic texture through synthetic and acoustic instrumentation in repetitive motions and extended durations, emitting distinct emotive, dynamic, and affective hues which bring forth a stunning depth of focus. Kali Malone’s recently released albums The Sacrificial Code [2019], Living Torch [2022], and Does Spring Hide Its Joy featuring Stephen O’Malley & Lucy Railton [2023] quickly rose to international critical acclaim, the latter charting #4 on The Billboard classical crossover chart. She has performed extensively, presenting her music at Hamburg Elbphilharmonie, Philharmonie de Paris, Venice Biennale, Radio France, Rockefeller Chapel, Grace Cathedral, The Southbank Center, Bozar, Schauspielhaus, Berghain, Unsound Festival, Berlin Atonal, Moogfest, and Kanal Pompidou amongst many other museums, contemporary art spaces, concert halls, churches, and festivals throughout Europe, North America, Japan and Australia.
