John Maddex talks with the team behind the Icons of Sound project that resulted in Cappella Romana's chart-topping surround-sound recording, Lost Voices of Hagia Sophia. He talked with the four people integral to the project: Alexander Lingas (Music Director of Cappella Romana), Bissera Pentcheva (Professor of Art and Art History, Stanford University), Jonathan Abel (Professor at the Center for Computer Research in Music and Acoustics, Stanford University), and Mark Powell (Executive Director of Cappella Romana).
