The Organization

Great Music under a Byzantine Dome is the concert ministry of the Greek Orthodox Archdiocesan Cathedral of the Holy Trinity in New York City. It programs a diverse series of concerts and performances every year, featuring performers from the Cathedral Choir and from the New York area, singing music from the sacred Orthodox tradition, the Greek folk and popular traditions, and Western classical and musical theater repertoire.

The Cathedral Music Ministry has a rich history of adding beauty to the Cathedral worship experience, performing the music of composers such as Theodore Bogdanos, Anna Gallos, Alexander Gretchaninov, Dimitrios Pappas, George Raptis, Nancy Takis, Tikey Zes, and many more, in addition to arrangements by the late Maestro Dr. Dino Anagnost, music director of the choir for many years. The renowned Cathedral Choir, formed by a core of music professionals and volunteers, is featured most Sundays at the Archdiocesan Cathedral.

Professor Baboukis is the conductor of the Cairo Choral Society, a community chorus affiliated with the University. Over the past eighteen years, he has conducted them in performances of major works in the Western choral repertory, including J.S. Bach’s Magnificat, Charpentier’s Messe de minuit and Te Deum, Handel’s Messiah, Haydn’s Creation and Nelson Mass, Mozart’s Requiem, Beethoven’s Mass in C and Choral Fantasy, Mendelssohn’s Elijah, Dvořák’s Mass in D Major, Brahms’s German Requiem and Schicksalslied, and Stravinsky’s Symphony of Psalms. He is also the conductor of the Cairo Festival Orchestra, a professional ensemble in residence at AUC.

In addition to accompanying the Cairo Choral Society, the Festival Orchestra presents concerto/aria concerts featuring student and faculty soloists, and concerts of orchestral repertory ranging from concerti grossi of Bach and Handel to Hindemith’s Symphony Mathis der Maler. He is the founder and co-director of the Lions of Cairo, a professional early music ensemble, with whom he is a singer, qanun player, and harpsichordist. The Lions present regular performances of Medieval, Renaissance, and Baroque Western music, Byzantine chant, and classical Arab music. He is a specialist in the performance of early music, and was the founder and director of the Saint Paul Early Music Ensemble and Les voix médiévales de Montréal.

Professor Baboukis holds a Doctor of Music degree from the Jacobs School of Music at Indiana University, where he was the first doctoral student ever permitted to submit an original composition (his Requiem Mass, for chorus, orchestra, and soloists) as a dissertation for a degree in choral conducting. He has written a substantial body of vocal music, as well as chamber works and music for piano, harpsichord, clavichord, and organ. In the past decade, his concerto for bassoon and string orchestra, Three Walks in Zamalek, and his Symphony for Cairo had their premiere performances by the Cairo Symphony Orchestra. He is currently composing a Symphony for Alexandria, which will be performed by the Chamber Orchestra of the Bibliotheca Alexandrina (the Great Library of Alexandria) in Alexandria and Cairo under his direction in March of 2023. 

He has been awarded a McKnight Composition Fellowship, and, in addition to receiving numerous private commissions, has twice won composer commissioning grants from the Jerome Foundation, through the American Composers Forum.
