of Vasily Petrenko as its next chief conductor, as of the 2013–2014 season, with an initial contract of 4 years. In November 2015, the orchestra announced the extension of Petrenko's contract through 2020. Petrenko concluded his chief conductorship of the orchestra at the close of the 2019–2020 season, with the season truncated by the COVID-19 pandemic. In May 2018, Klaus Mäkelä first guest-conducted the orchestra. On the basis of this appearance, in October 2018, the orchestra announced the appointment of Mäkelä as its next chief conductor, effective with the 2020–2021 season, with an initial contract of 3 seasons. In May 2020, the orchestra announced an extension of Mäkelä's initial contract with the orchestra for an additional 4 seasons, unusual in its timing before the official start of his tenure as chief conductor of the orchestra. Other recordings by the orchestra include a series of Bartók recordings for Simax, completed in 2000. The orchestra has won various recording prizes, including the Grand Prix du Disque, Diapason d'Or, and the German Classical Music Award. The orchestra and Mäkelä have recorded a set of the complete Sibelius symphonies for Decca.
