(George) Calvin Hampton (December 31, 1938 – August 5, 1984) was a leading American organist and sacred music composer.
From September 1963 through June 1983, he was organist and choirmaster at Calvary Episcopal Church in the Gramercy Park neighborhood of Manhattan.
In 1974, he composed music for Walter Leyden Brown's production of Herman Melville's Pierre, or the Ambiguities, which was produced at La MaMa Experimental Theatre Club in the East Village of Manhattan.
"[2] His settings of the Episcopal liturgy are also used in Catholic churches [citation needed], and his choral works are innovative and challenging pieces of sacred music.
He contracted AIDS but remained active until the final few weeks of his life, composing the massive Alexander Variations for two pipe organs while almost completely bedridden in 1984.
