A Mighty Fortress Is Our God
Shortly thereafter, Eastman settled in New York City, where he initially straddled the divide between the conventionally bifurcated "uptown" and downtown music scenes. Eastman often wrote his music following what he called an "organic" principle. Each new section of a work contained all the information from previous sections, though sometimes "the information is taken out at a gradual and logical rate." The principle is most evident in his three works for four pianos, "Evil Nigger", "Crazy Nigger", and "Gay Guerrilla", all from around 1979. The last of these appropriates Martin Luther's hymn, "A Mighty Fortress Is Our God," as a gay manifesto.
