Since the late 1970s, Pärt has worked in a minimalist style that employs his self-invented compositional technique, tintinnabuli. Pärt's music is in part inspired by Gregorian chant. His most performed works include "Fratres" (1977), "Spiegel im Spiegel" (1978), and "Für Alina" (1976). Pärt has been the most performed living composer in the world for five consecutive 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.
