The ensemble is known especially for its presentations and recordings of medieval Byzantine chant (the Eastern sibling of Gregorian chant), Greek and Russian Orthodox choral works, and other sacred music that expresses the historic traditions of a unified Christian inheritance. Since 2011, they have performed and recorded music with the Icons of Sound project. Their collaborations include two Stanford Live concerts in the Bing Concert Hall and the resultant recording, Lost Voices of Hagia Sophia, first vocal album to be recorded entirely in virtual acoustics.
Ravinder S. Binning was research assistant for the Aural Architecture seminar sponsored by the Onassis Foundation, 2013-14. Binning worked as an aid from the project’s beginnings as a seminar with guest speakers to its final completion as a book: Aural Architecture in Byzantium: Music, Acoustics and Ritual, edited by Bissera V. Pentcheva (Abingdon, Oxon/New York: Routledge, 2018). ). Binning assisted presentations and also assisted in editing the book manuscript, and contributed the chapter entitled Christ’s All-Seeing Eye in the Dome, which considered the deep origins of “panoptic architecture,” tracing the origins of a modern architectural disciplinary phenomenon to an undiscovered Byzantine past. Thanks to the inspiration of this seminar, Binning launched inquiry a dissertation on the relationship between fear and the construction of Christian art in the Mediterranean world. The 2018 dissertation was subsequently awarded a three-year grant from the Center for Advanced Study in the Visual Arts, National Gallery of Art.

Fernando Lopez-Lezcano, Stanford University, CCRMA Faculty/Staff (Researcher, Systems Administrator, Lecturer). Fernando Lopez-Lezcano enjoys imagining and building things, fixing them when they don’t work, and improving them even if they seem to work just fine. The scope of the word “things” is very wide, and includes computer hardware and software, controllers, music composition, performance and sound. His music blurs the line between technology and art, and is as much about form and sound processing, synthesis and spatialization, as about algorithms and custom software he writes for each piece. He has been working in multichannel sound and diffusion techniques for a long time, and can hack Linux for a living. At CCRMA, Stanford University since 1993, he combines his backgrounds in music (piano and composition), electronic engineering and programming with his love of teaching and music composition and performance. He discovered the intimate workings of sound while building his own analog synthesizers a very very long time ago, and even after more than 30 years, “El Dinosaurio” is still being used in live performances.

Danny Smith is a doctoral candidate in the Department of Art and Art History at Stanford University. His dissertation, “Dreaming in Public in Late Medieval Rome,” examines the pictorial, theological, and intellectual histories of dreams and dreaming in thirteenth-century Italian art. In conjunction with the Icons of Sounds project, Smith and Lora Webb co-produced Façade, an exhibition entitled that presented a 5-channel video of the façade of Mission Santa Clara de Asis from sunrise to sunset on a single day. Each screen played a different hour of the day, dramatizing the effects of time and light on architecture. The exhibition culminated in a live projection of the film during the 2016 Icons of Sound Symposium. In 2017 they produced a similar exhibition, Chapel, for Stanford’s Coulter Gallery. For Chapel they filmed the façade of the Calera Chapel near Balmorhea, Texas from sunrise to sunset and projected this footage into five screens in asynchronous loops, immersing a viewer within the façade and landscape’s changes over the course of a day. A smaller gallery laid out to match the chapel’s interior featured ambient audio recorded during the filming: marking time in the chapel’s tolling bell, the rare passing car, and the steady whine of cicadas.
Laura Steenberge became involved with the Icons of Sound project while working towards a DMA in music composition at Stanford, a composer and performer. In 2014 Steenberge began working with Pentcheva on a research project about text painting in medieval Byzantine chant, culminating in a paper, “We Who Musically Represent,” included in the Aural Architecture book. The project investigated how musical icons were employed in medieval settings of the Cherubikon, a hymn that originated in the Hagia Sophia during the sixth century. Since the completion of this project, Steenberge continues work with Pentcheva on transcriptions of musical chant that illuminate instances of text painting, and in creative practice, performs and composes works influenced by chant, ritual practices imaginary music (fictitious or hypothetical sounds that exist primarily as text descriptions, such as the singing of the sirens or the Big Bang). A few recent projects that emerged from these studies include Byzantine Rites, a series of site-specific performance pieces; Harmonica Fables, a collection of recordings for harmonica; and The Imaginary Music Radio Hour, a monthly show about music, mythology and shape.
Lora Webb is a PhD candidate in art history at Stanford University. She collaborated in the creation of an art piece, Façade, along with Danny Smith for the conference “Icons of Sound: Voice, Architecture, Imagination” held in November of 2016. The installation provided the chance to view the building in real time, and to see the dramatic change the day brings to the static structure from the rainy morning, to the sunny afternoon, to just after dusk. Through headphones, viewers could also hear the ambient sounds available on that day, including the church bells, sounds of the mass filtering through the door, and even skateboarding students. Webb also published an essay on ritual and the monastic church at Nea Moni on the island of Chios in the collection Aural Architecture in Byzantium (edited by Bissera V. Pentcheva, 2018). The article, entitled “Transfigured: mosaic and liturgy at Nea Moni,” focuses on the liturgical activities of a single day, August 6, the feast of the Transfiguration, and the mosaic depicting the same subject. Webb’s dissertation “Kosmos Embodied: Eunuchs and Byzantine Art in the Ninth through Twelfth Centuries” asks how eunuchs were visually present in the Byzantine court, exploring concepts of liminality within manuscripts, metalwork, and ritual. It addresses their artistic patronage, how they are represented, and, because they are “made” through the act of castration, how they themselves functioned as aesthetic objects within the ceremony of the court.
