The Latvian Radio Chamber Singers (LRCS), established by Kaspars Putniņš in 1994, is a vocal ensemble formed by members of the Latvian Radio Choir. The group (8 to 16 singers) explore the human vocal and novel forms of expression. Along with regular concert programmes of the 20th/21st century music written by contemporary composers and performance of experimental contemporary scores, the group is involved in stage productions. The cooperation with Danish installation/performance theatre Hotel Pro Forma and stage auteur Kirsten Dehlholm has been a success story – three multimedia choral operas in 10 years. The first teamwork resulted in the much accredited Operation: Orfeo (2007), and it was followed by War Sum Up (2011) and NeoArctic (2016).
