Chris Fritzsche Head ShotChris Fritzsche, soprano, is a native of Santa Rosa CA. He has been a “performer” since the tender age of two, when he was first dragged (literally) across the stage, playing the part of young Michael’s teddy bear in the play, Peter Pan. Flush with such early success, he took up the guitar at age seven and immersed himself in music of the Beatles, Simon & Garfunkel, James Taylor, and John Denver, among others. He discovered the joys of choral singing in high school and went on to study voice in college as a tenor. Several leading musical theatre and opera roles later, he graduated with a degree in music, and was about to get a real estate license (in order to satisfy his Capricorn desire for money) when someone informed him that the falsetto voice he had only ever used in jest could actually be put to use on the concert stage. This led him to join the men’s ensemble Chanticleer as a soprano for the next 11 years, performing in many of the world’s greatest concert halls and singing on well over a dozen recordings, two of which won Grammy Awards. Having retired from the road in 2003, he has since expanded his solo and ensemble career, appearing with various groups and artists in the San Francisco Bay Area and beyond. He served on the vocal faculty at his alma mater, Sonoma State University, from 2004 to 2009. He continues to teach vocal classes and performs regularly with the Sonoma Bach early music organization. He is currently the Music Director for the Center for Spiritual Living in Santa Rosa.

An active teacher as well as performer, Justin taught voice for the University of Minnesota and toured Minnesota and the upper Midwest, performing with many ensembles including the Minnesota Opera, the Minnesota Orchestra, Western Plains Opera, and the Des Moines Symphony.
