About Illuminati

Four years ago, Tony Thornton began Illuminati Vocal Arts Ensemble with a mission to create a professional-caliber vocal arts ensemble with the heart and dedication of an amateur chorus. Dr. Thornton is well acquainted with professional ensembles, as you can see from his biography.

The Illuminati Vocal Arts Ensemble is beginning to realize Tony’s vision. A unique chamber chorus, we draw our volunteer singers from throughout Massachusetts and beyond. We have received rave reviews from audiences and newspapers, and have earned the respect of area cultural institutions.

The ensemble performs choral miniatures and masterworks from all periods and styles, and collaborates with other community/professional organizations.

“Performances at the level of Illuminati's give the listener a clear window into the composer's soul.” - Clifton Noble Jr, The Republican, Oct. 15, 2016

After successful collaborations with Joseph Flummerfelt and Ian Watson in October, our season continues in 2018 with a performance of the Rachmaninoff All-Night Vigil with the UMass Chamber Chorus on February 24 (details below). On April 28, we will perform the Verdi Messa da Requiem with the Springfield Symphony Orchestra and Chorus. Finally, our season will close with a solo outing of Baroque music at Grace Church in Amherst on June 16, when we will present a program centered on Bach’s Christ Lag in Todesbanden. A favorite piece of John Eliot Gardiner, he has called it “a bold, innovative piece of musical drama.”

Illuminati will perform Rachmaninov’s All-Night Vigil on Saturday, February 24, 2018, at 8:00 pm at Our Lady of the Valley Catholic Church, 33 Adams St., Easthampton. We will be joined by the UMass Chamber Choir, also under the direction of Tony Thornton.

The All-Night Vigil, a work of almost unbearable beauty, is regarded as the pinnacle of Russian Orthodox choral music, and is one of the most challenging pieces in the a cappella repertory.

Rachmaninov composed it in under two weeks, early in 1915, when he had just spent a year touring cities in support of Russian troops. Its 15 texts, which span Vespers through Matins to Prime, are his response to the chaos and suffering of World War I. Nine of the movements are based on traditional chant; the other six are original. In mood, they move from praise to meditation, from penitence to appeals to God to deliver humankind from death and calamity. Crystalline pianissimos suddenly swell into enormous full-throated cries and then subside again. Soprano lines float ethereally over bass notes so low they seem almost beyond the range of human hearing. The music makes enormous demands on singers’ intonation, breath control and emotional engagement.

At the time of its composition, the All-Night Vigil was seen as the masterpiece that would breathe new life into the tradition of Russian Orthodox liturgical music, but history turned in another direction. In post-revolutionary Bolshevik Russia, religious expression was suppressed, and church choirs were disbanded. The Vigil was not recorded until 1965. Rachmaninov left Russia in 1917, in the wake of the Bolshevik revolution and the seizure of his family’s estate. He fled to Finland and eventually the U.S. He considered the All-Night Vigil one of his finest works, and in his will asked that it be sung at his funeral and that he be buried in Moscow. But he died in 1943, in Beverly Hills, and he was buried in Westchester, N.Y., and his wish went unfulfilled.


Entrance into the ensemble is by audition only (see audition process below). Dr. Thornton seeks singers with considerable choral experience. While perfect sight reading is not required, all singers must fully prepare repertoire before the first rehearsal. Illuminati makes music from the beginning.

Dr. Thornton is building an ensemble with a beautiful, communicative sound: tall, warm, vibrant, and round vowels; a wide dynamic palette; an inner rhythmic drive; and in-tune and balanced resonance. In the soprano section he is looking for lyric, energized purity; in the alto section a rich, full sound; in the tenor section a lyric, high/forward, yet warm sound; and in the bass section a rich baritone sound with forward placement that is not overly dark.

If you are interested, please complete the form here and we will email you an audition confirmation with possible times.

Audition Process:
The audition takes approximately ten minutes. Singers will be asked to perform scales using a variety of articulations (legato, staccato, and marcato) and dynamics to demonstrate color, range, quality, and flexibility. A segment of the audition will emphasize sight-reading and tonal memory (with accompaniment). Finally, each singer should prepare his or her vocal part of this PDF excerpt from BWV 76 (Die Himmel erzählen die Ehre Gottes, measures 20-36 only). The excerpt will be sung without accompaniment. Singers should perform as close to quarter=96-100 as possible. German is preferred, but a neutral syllable may be used.
