One Collective Breath: Janet Cardiff’s ‘The Forty Part Motet’ | KQED Arts

‘Canadian artist Janet Cardiff’s “The Forty Part Motet,” is deceptively simple in appearance: a spare room occupied solely with a ring of black speakers on stands. But once the first collective breath of the virtual choir begins, and the forty part harmonies of Thomas Tallis’s masterful choral work ripple throughout the gallery, the “mind-boggling” complexity of her sound sculpture becomes apparent.‘
