Based in Leipzig, the MDR Leipzig Radio Chorus is the largest choir in the Mitteldeutscher Rundfunk (Central German Radio) Broadcasting Corporation, and it has become one of the leading choral ensembles in Europe. Originally formed in 1924, then reformed on May 1, 1946, and incorporated on August 1 that year, the ensemble became the Kammerchor (Solistenvereinigung) Leipzig, and it has performed for radio broadcasts and concerts with the MDR Leipzig Radio Symphony Orchestra and in its own right as a chamber choir. Over its history, the ensemble has been directed by Heinrich Werlé, Herbert Kegel, Wolf-Dieter Hauschild, Jörg-Peter Weigle, Gert Frischmuth, Howard Arman, and Philipp Ahmann. The MDR Leipzig Radio Chorus won the European Cultural Award in 2013, and performed at the ceremonies. Since 2015, the choir has been directed by Risto Joost. The choir received the International Classical Music Award in 2017 for its recording of Reger's Motets, Op. 110, and was given the Diapason d'Or for its release of Rachmaninov's Vespers (All-Night Vigil) on Genuin, its second recorded version under Joost's direction.
