The Estonian Philharmonic Chamber Choir (EPCC) is a professional choir based in Estonia. It was founded in 1981 by Tõnu Kaljuste, who was its conductor for twenty years. In 2001, Paul Hillier followed Kaljuste's tenure, becoming the EPCC's principal conductor and artistic director until September 2008, when Daniel Reuss took over the task. The repertoire of the EPCC ranges from Gregorian Chant to modern works, particularly those of the Estonian composers Arvo Pärt and Veljo Tormis. The group has been nominated for numerous Grammy Awards, and has won the Grammy Award for Best Choral Performance twice: in 2007 with Arvo Pärt's Da pacem and in 2014 with Pärt's Adam's Lament, the latter was shared with Tui Hirv & Rainer Vilu, Sinfonietta Riga & Tallinn Chamber Orchestra; Latvian Radio Choir & Vox Clamantis.
