After using the piece for several years at Chrism Mass in Orlando and Baltimore, I finally was able to capture a live performance recording to share. This was recorded (on my iPhone) at the Chrism Mass at the Cathedral of Mary Our Queen in Baltimore on 10 April 2017. The Archdiocesan choir had one rehearsal with the piece, though some of the people have sung it previously. There is a brass quintet playing choir two.
