Henryk Mikołaj Górecki was a Polish composer of contemporary classical music. According to critic Alex Ross, no recent classical composer has had as much commercial success as Górecki. He became a leading figure of the Polish avant-garde during the post-Stalin cultural thaw. His Anton Webern-influenced serialist works of the 1950s and 1960s were characterized by adherence to dissonant modernism and influenced by Luigi Nono, Karlheinz Stockhausen, Krzysztof Penderecki and Kazimierz Serocki. He continued in this direction throughout the 1960s, but by the mid-1970s had changed to a less complex sacred minimalist sound, exemplified by the transitional Symphony No. 2 and the Symphony No. 3. This later style developed through several other distinct phases, from such works as his 1979 Beatus Vir, to the 1981 choral hymn Miserere, the 1993 Kleines Requiem für eine Polka and his requiem Good Night.
