Antal Doráti
By the time of his Symphony No. 5, completed in 1962, his mobility and health were compromised considerably. In 1964, the government granted him a lifelong guaranteed income. His greatest success came a few years later with his (1966), which premiered on 13–October 1968 in Stockholm Concert Hall with Antal Doráti conducting the Stockholm Philharmonic Orchestra. A recording of his seventh symphony, with the same conductor and orchestra, was released in 1969. It was a breakthrough, establishing his international reputation, and he received two Swedish Grammis in 1970. The conductors Antal Doráti and Sergiu Comissiona premiered and made first recordings of several of Pettersson's symphonies and contributed to his rise to fame during the 1970s.
