Since 1968, Pacific Chorale has provided regional, national, and international audiences with distinctive performances of classical and contemporary choral works. Under the leadership of Artistic Director John Alexander, the 160-voice Pacific Chorale and the 30-voice JOHN ALEXANDER SINGERS present a concert series each year at the Orange County Performing Arts Center. Pacific Chorale also serves as the resident chorus for Pacific Symphony and performs regularly with the Los Angeles Philharmonic and the Hollywood Bowl Orchestra. The John Alexander Singers, Pacific Chorale's professional chamber ensemble, has performed with the Mark Morris Dance Company, the Royal Ballet, the L.A. Chamber Orchestra, the Pacific Symphony, and the Philharmonia Baroque Orchestra, and have been featured artists in the Philharmonic Society's Eclectic Orange Festival.

Artistic Director of Pacific Chorale since 1972, John Alexander has conducted his singers with orchestras throughout Europe, Asia, the former Soviet Union, and South America and, closer to home, with Pacific Symphony, the Pasadena Symphony, Musica Angelica, and the L.A. Chamber Orchestra. Alexander has prepared choruses for many of the world's most outstanding orchestral conductors, including Seiji Ozawa, Leonard Slatkin, Zubin Mehta, Esa-Pekka Salonen, Pierre Boulez, Lukas Foss, Keith Lockhart, John Mauceri, Michael Tilson Thomas, Gerard Schwarz, and Max Rudolf.
