(March 1, 2022, St. Louis, MO) – Acclaimed conductor Patrick Summers, the Artistic and Music Director of the Houston Grand Opera, will make his debut with the St. Louis Symphony Orchestra on short notice this weekend, leading the SLSO, St. Louis Symphony Chorus, Principal Horn Roger Kaza, and a quartet of soloists including soprano Erica Petrocelli, mezzo-soprano Jennifer Johnson Cano, tenor Nicholas Phan, and bass Soloman Howard in an all-Mozart program at Powell Hall, March 4-6. Cano also steps in on short notice to sing "Non più di Fiori" from La Clemenza di Tito, in addition to performing on Mozart's Requiem. Kaza steps in to perform W.A. Mozart's Horn Concerto No. 2.

Summers replaces Dmitry Sinkovsky, who was scheduled to conduct the SLSO, perform on violin, and sing with the orchestra in his SLSO debut. Sinkovsky is unable to travel to St. Louis this week.

Instead of the previously announced first half of works by J.C. Bach, Antonio Vivaldi, and G.F. Handel, the SLSO will instead perform an all-Mozart program, including the La Clemenza di Tito Overture; "Non più di Fiori" from the opera La Clemenza di Tito; and Horn Concerto No. 2. The SLSO, St. Louis Symphony Chorus, and soloists Erica Petrocelli (soprano), Jennifer Johnson Cano (mezzo-soprano), Nicholas Phan (tenor), and Soloman Howard (bass) will perform Mozart's Requiem as scheduled.

A leading proponent for contemporary American opera and a regular guest at many of the world's leading opera houses, Patrick Summers has fostered and given more than 20 world premieres, collaborating with many of today's most prominent and performed composers, among them Carlisle Floyd, Christopher Theofanidis, and Philip Glass. Summers conducts a wide range of repertoire from Baroque to bel canto to German Romantic.

Roger Kaza rejoined the St. Louis Symphony Orchestra as Principal Horn in the fall of 2009. He has appeared with the SLSO as a soloist numerous times, most recently on December 31, 2021, giving the world premiere of Stefan Freund's Voyageur Fantasy, a work that celebrates the bicentennial of Missouri.
