Riga Cathedral
"Missa Rigensis" (2002) was written for and first recorded by the Riga Cathedral Boys Choir, conducted by Mārtiņš Klišāns. In 2008 conductor Stephen Layton recorded Missa Rigensis with the Choir of Trinity College of Cambridge. The recordings were released on CD titled "Baltic Exchange" on the Hyperion Records label. Prauliņš stated that his desire in composing the piece was "to retain attention by the singers' voices alone."
