The vocal group Cappella Romana has become identified with its specialty in Eastern Orthodox vocal traditions, both Byzantine and Slavic. The group has also commissioned virtuoso vocal music from several contemporary composers. Cappella Romana was formed in 1991 in Portland, Oregon, and continues to be based there. Its conductor is Alexander Lingas. Cappella Romana has emphasized mastery of the original languages of music from the Eastern Orthodox world, including Koine Greek and Old Church Slavonic, but has also released the album Lay Aside All Earthly Cares: Orthodox Choral Works in English. The group released five albums in the early and middle 2020s, including a pair in 2023, A Byzantine Emperor at King Henry's Court, and Arvo Pärt: Odes of Repentance.
