San Francisco-based Philharmonia Baroque Orchestra has announced its exciting 2022-23 season spotlighting rare works by Handel and featuring Anthony Roth Costanzo, along with 13 guest artist debuts.

Here’s what’s in store for Bay Area audiences. For this article, only vocal performances are listed.

First up is Händel’s oratorio “Theodora,” featuring mezzo-soprano Helen Charlston in her PBO and American debut, soprano Julie Roset in her PBO debut, countertenor Aryeh Nussbaum Cohen, tenor Thomas Cooley, and bass-baritone Dashon Burton. The last time PBO presented the work was in 1991.

Performance Dates: Oct. 20-23, 2022

With December comes performances of Händel’s “Messiah.” Music Director Richard Egarr will lead the full PBO Orchestra and Chorale in the epic oratorio featuring mezzo-soprano Rihab Chaieb in her PBO debut, soprano Stefanie True, tenor Andrew Tortise, and bass Joshua Bloom.

Performance Dates: Dec. 14-18, 2022

In February 2023, PBO will present the alternative concert series Sessions. Creative Partner Davóne Tines, conductor and keyboardist David Belkovski, and soprano Nola Richardson, designed the 2022 installment entitled “The Artist as Human.” Participating artists will discuss their connections with the music they perform and how themes of gender, race, and sexuality surface in works new and old. Compositions by J.S. Bach, John Blow, Henry Purcell, Tarik O’Regan, and Katherine Balch, among others, will be examined.

Performance Dates: Feb. 16-17, 2023

In its first co-production with Boston Baroque, PBO brings together countertenor Anthony Roth Costanzo, sopranos Deanna Breiwick and Nicole Heaston, and countertenor Kangmin Justin Kim in a staging of Händel’s dramatic opera “Amadigi di Gaula.” Met Opera and Lyric Opera of Chicago staff director Louisa Muller will direct the production. The opening night performance will be PBO’s 2023 Spring Gala. Richard Egarr will be on the podium.

Performance Dates: Apr. 20-22, 2023

Closing the season will be the presentation of the rarely performed “Missa in labore requies (Muffat Mass).” The work for orchestra, chorus, and eight soloists will showcase the PBO Orchestra, Chorale, sopranos Maya Kherani and Nola Richardson, countertenors Reginald Mobley and Siman Chung, tenors James Reese and Spencer Britten, and bass-baritones Cody Quattlebaum and Jonathan Woody. Also on the program is orchestral music by Biber and Schmelzer juxtaposed with a new work by the disruptive 21st-century composer Mason Bates.
