Mikis Theodorakis is a Greek composer who has set many liturgical services to orchestral music with choirs singing them beautifully to his own melodies. In his Requiem he presents the Memorial Service of the Church with a full orchestra and huge, polyphonic choir. In the background, the tubular bells are played in the rubrics of the bell-ringing for a funeral and Good Friday (each bell is struck once from smallest to largest then repeated). He has conducted his works across the world, and has thus presented the prayers of the Church to people who would not normally encounter them.
Yes, I think it's artsy, and certainly wouldn't think such works should be used liturgically, but they can certainly act as "ambassadors" for the beauty of the Orthodox Church- and perhaps someone who experiences them may want to learn more.
