Kaspars Putniņš started as an artistic director and chief conductor of the Estonian Philharmonic Chamber Choir in September 2014. He has been the conductor of the Latvian Radio Choir since 1992. In 1994, he formed the Latvian Radio Chamber Singers, an ensemble of soloists formed from the members of Latvian Radio Choir. He regularly appears as a guest conductor with leading European choirs such as the BBC Singers, RIAS Kammerchor, Estonian Philharmonic Chamber Choir, Berliner Rundfunkchor, NDR Kammerchor, Netherlands Radio Choir, Collegium Vocale Gent, Flamish Radio Choir and others.
Whilst Kaspars Putniņš work encompasses a wide range of choral repertoire from Renaissance polyphony to works of the Romantic period, his foremost goal has always been that of promoting new outstanding choral music. This new repertoire challenges and develops the abilities of his performers and takes their vocal sound to entirely uncharted territories.
Kaspars Putniņš has also initiated several theatrical projects, which involve the participation of his choir, in collaboration with visual and theatre artists. He often lectures and gives master classes internationally.
Kaspars Putniņš is the recipient of the Latvian Music Grand Prix (1998), the Latvian Council of Ministers Award for Achievements in Culture and Science (2000) and the Order of the Cross of Terra Mariana, 4th Class, by the Estonian President (2019).
