A disciple of Arnold Schoenberg, Anton Webern was a key member of the so-called Second Viennese School, his music notable for its extraordinary concision, aphoristic nature and serialist exactitude. Webern’s own life was cut short in 1945 when he fell victim to a shot from an American sniper at the end of World War II. His orchestral tone poem Im Sommerwind (In the Summer Wind) demonstrates the origins from which his mature style later grew: an atmospheric early work dating from 1904, it is steeped in rich, Straussian late romanticism. It was only premiered years after his death. Mariss Jansons and the Royal Concertgebouw Orchestra give a raptly gorgeous performance.
