Loren Rush (born August 23, 1935) is a U.S. composer.
His works include the drone piece Hard Music (1970) for three amplified pianos.
The piece features no melodic figuration but rather clouds created by only one note, the low D above cello C, repeated quickly enough by each player to be heard as nearly continuous.
[1] In 1957, he formed an improvisation group with Terry Riley, Pauline Oliveros, Robert Erickson, and Bill Butler with a focus an aleatoric and improvisational techniques.
