Founded in 1991, Cappella Romana’s name refers to the medieval Greek concept of the Roman oikoumene (inhabited world), which embraced Rome and Western Europe, as well as the Byzantine Empire of Constantinople (“New Rome”) and its Slavic commonwealth. Flexible in size according to the demands of the repertory, Cappella Romana has a special commitment to mastering the Slavic and Byzantine musical repertories in their original languages, thereby making accessible to the general public two great musical traditions that are little known in the West. In the field of contemporary music, Cappella Romana has taken a leading role in bringing to audiences the vocal works of such European contemporary composers as Michael Adamis , Ivan Moody, Arvo Pärt, and John Tavener, as well as promoting the work of North Americans such as Fr. Sergei Glagolev, Christos Hatzis, Peter Michaelides, and Tikey Zes. The vocal ensemble presents annual concert series in Portland, Oregon and Seattle, Washington, in addition to touring nationally and internationally. Critics have consistently praised these for their unusual and innovative programming, including numerous world and American premieres. The group regularly collaborates with such artists as conductor Paul Hillier, chant specialist Ioannis Arvanitis, and composer Ivan Moody. The ensemble is based in Portland, Oregon, in the Pacific Northwest of the United States.
