Dale Warland Singers

The Dale Warland Singers (DWS) was a 40-voice professional chorus based in St. Paul, Minnesota, founded in 1972 by Dale Warland and disbanded in 2004. They performed a wide variety of choral repertoire but specialized in 20th-century music and commissioned American composers extensively. In terms of sound, the DWS was known for its purity of tone, intonation, legato sound and stylistic range. During their existence, the DWS performed roughly 400 concerts and recorded 29 CDs. wikipedia
