Poul Ruders (born March 27, 1949 in Ringsted) is a Danish composer. Ruders's early studies in piano and organ led eventually to studies in orchestration with the Danish composer Karl Aage Rasmussen. His first compositions date from the mid-60s. Ruders regards his own compositional development as a gradual one, with his true voice emerging with the chamber concerto, Four Compositions, of 1980. Writing about Ruders, the English critic Stephen Johnson states: "He can be gloriously, explosively extrovert one minute-withdrawn, haunted, intently inward-looking the next.
