Silvestrov (1937) is a Ukrainian composer whose works are mainly in a postmodern style. His extensive song cycle Silent Songs for baritone and piano from 1974 is for me one of the most beautiful song cycles of all time. To quote one critic: "Silent Songs is like no other song cycle you've heard. Completely eschewing overt expression, drama, and vocalism, lasting nearly two hours in performance, and remaining always as soft as humanly possible, it drifts through the air in an irresolute haze -- never competing for your attention, but never allowing you to forget it's there."
