William Basinski and Kali Malone co-headline Knockdown Center on Sept. 4. One of the foremost voices in modern ambient music, Basinski's "The Disintegration Loops" is widely revered as an iconic entry into the canon. His mercurial, grief-stained works transcend the limits of the form, serving as quietly gripping treatises on loss whose stark simplicity and pure marriage of form and function reaches transcendent heights. Composition phenom Kali Malone is renowned for her organ works and ensemble writing, Malone reimagines renaissance music through a deep, drone-heavy minimalism. Malone's recent "All Life Long" is an unexpected breakout hit, winning equal acclaim in the avant garde and amongst a broad, global audience. San Francisco noise performer Evicshen opens the night with a feverish, ferocious set of power electronics. Knockdown Center 21+
