Meet the musicians who make the music that makes our wonderful concerts!


Amanda Balestrieri

is widely recognized as “a musician’s singer.” She took her rigorous instrumental training in orchestral and chamber music. Combining this with her love of language and the stage, she crafted an unusually versatile soprano voice in the classical music community. Born in England, she won two scholarships to Oxford University where she received her BA/MA in German and French, and studied voice in London with Marjorie Thomas of the Royal Academy of Music and Milan with Maria Luisa Cioni. She sang with the Academy of St. Martin in the Fields under Sir Neville Marriner for the soundtrack of the movie Amadeus and was a regular soloist in contemporary music with James Wood’s New London Chamber Choir. 

After moving to the United States, Balestrieri made several notable appearances with the National Symphony under Leonard Slatkin and Christopher Hogwood, and with the Smithsonian Chamber Players under Kenneth Slowik. Renowned for her “radiant intelligence” and her “unusually versatile” voice with its “luminous warmth” (Washington Post, Santa Fe New Mexican), she is in high demand for her musicianship and skills in baroque repertoire. Her teachers included Martha Ellison and Mary Ann Stabile. She has appeared with the major period instrument ensembles throughout the U.S., including New York Collegium, Concert Royal and New York Baroque Dance Company, Opera Lafayette, Washington Bach Consort, and American Bach Soloists.

In the Denver area, Balestrieri has been a guest soloist with area symphony orchestras and ensembles, including the Colorado Symphony and the Colorado Chamber Players, and with period instrument ensembles including Baroque Chamber Orchestra of Colorado, Seicento Baroque Ensemble, Boulder Bach Festival, and Parish House Baroque. Formerly on the Voice Faculty at the University of Virginia, she taught Voice Performance at Regis University in Denver for several years.
