It isn't every day — or even every century — that people get to hear an orchestra's inaugural performance in their own city. The Orchestra San Antonio (TOSA) is making its debut on Saturday, March 29, at the Tobin Center’s H-E-B Performance Hall.

Things are different in San Antonio, where orchestras have been coming and going with surprising frequency. Following an 83-year history and a nine-month strike, the Symphony Society of San Antonio declared bankruptcy and dissolved in 2022. The San Antonio Philharmonic was waiting in the wings to immediately take its place, and it just moved into a new venue, the Scottish Rite Auditorium, making its debut there early this February.

Now another new orchestra is joining the mix. TOSA, formerly the Classical Music Institute Orchestra, is presenting itself as a new group while continuing to operate under the Classical Music Institute, which resides at the Tobin Center.

"Established as a resident orchestra of the Tobin Center for the Performing Arts, TOSA is dedicated to presenting a dynamic range of artistic programming and community engagement efforts that highlight its commitment to innovation, education, and the arts," says a mission statement provided in a press release announcing the debut concert.

The first concert, called Echoes in Diversion, will present classical, Spanish, and Latin American music under the direction of Venezuelan principal conductor Leonardo Pineda. It will also feature two Venezuelan soloists: trumpetist Pacho Flores and mezzo-soprano Zaireth Pérez. This is the first time either soloist will play in San Antonio.

The program is as follows:

• Manuel de Falla — The Three-Cornered Hat, Suite 1: An excerpt from a 1919 Spanish ballet
• Arturo Márquez — Concierto de Otoño: A 2018 trumpet concierto by a Mexican composer
• Aldemaro Romero — Fuga con Pajarillo: A 1990 fugue that gained famous Venezuelan conductor Gustavo Dudamel early-career international attention in 2004
• Astor Piazzolla — Tangazo: Variations on Buenos Aires: A 1969 piece by an Argentine nuevo tango trailblazer
• Juan Pablo Contreras — Mariachitlán: A Mexican composer's 2022 homage to his home state of Jalisco, where mariachi originated

Flores will also pay a visit to students at Ronald Reagan High School, where he'll give a special presentation and masterclass. He'll also bring his collection of Stomvi trumpets, which are made in Valencia, Spain.

Tickets ($15-69) for the inaugural TOSA concert Echoes in Diversion are available at tobincenter.org. The performance starts at 7:30 pm.
