[1] It was founded in 1964 by Roger Wagner to be one of the three original resident companies of the Music Center of Los Angeles County.

[citation needed] The Master Chorale regularly performs with the Los Angeles Philharmonic and the Hollywood Bowl Orchestra, both at the Music Center and at the Hollywood Bowl, with such leading conductors as Gustavo Dudamel, Esa-Pekka Salonen, Zubin Mehta, André Previn, Pierre Boulez, Michael Tilson Thomas and Roger Norrington, among many others.

Debuting in 2016, singers from the Los Angeles Master Chorale transform this 75-minute work into an emotional performance piece centered around the Apostle Peter accepting responsibility and the seven stages of grief that he experienced after disavowing his knowledge of Jesus on the day he was arrested.

In July 2019, Lagrime di San Pietro had the prestigious honor of performing the opening concerts that season's Salzburg Festival in Austria.

[10] "Voices Within," another of the Chorale's highly successful outreach programs, is an in-depth, ten-week, in-school residency program for middle and high school students that helps children who have little or no musical background to “find their voices.” With the assistance of a teaching artist, lyricist, and composer who work with teams of students in the classroom, children write music and lyrics to create original songs.
