Lost Voices of Hagia Sofia

Cappella Romana at Stanford University: in 2013 and 2016.

The sound of 500 year old choral music in the Hagia Sofia.

Lost Voices of Hagia Sophia” is the first vocal album in the world to be recorded entirely in live virtual acoustics. It brings together art history, music history, performance, and technology to re-create medieval sacred sound in the cathedral of Hagia Sophia as an aural virtual reality.
