Peruvian-American mezzo-soprano Kelly Guerra is widely recognized for her distinctive voice, described as “rich and sultry, radiating warmth and power, with a smoky timbre” Isthmus News (2025).

Her 2025-2026 season has included the premiere of the new opera about the iconic Chicana activist Dolores by Nicolás Lell Benavides and Marella Martin Koch at West Edge Opera and Opera Southwest. In the spring and summer of 2026 Kelly looks forward to singing Sesto in Giulio Cesare with Opera Santa Barbara, Franca Naccarelli in The Light in the Piazza with Opera Theatre of Saint Louis and Ariel in The Tempest by Joseph Summer at Teatro Grattacielo.

For the 2026-27 season, Kelly will perform with the NFM Wrocław Philharmonic in Iphigenia by Wayne Shorter and star in Ofrenda by Jorge Sosa with Austin Opera. Kelly looks forward to debuting the role of Carmen at Opera San Jose in 2027 as well as reprising her signature role of María in María de Buenos Aires with Opera Orlando.

Career highlights include her Metropolitan Opera debut as one of the Niñas in Golijov's flamenco opera Ainadamar, Jo March in Mark Adamo's Little Women with Fort Worth Opera, Rosina in Il barbiere di Siviglia with Opera Las Vegas, Isabella in L'italiana in Algeri with Anchorage Opera and Opera in the Heights, María in María de Buenos Aires with Madison Opera, and Mrs. Fox in Fantastic Mr. Fox with Opera Omaha.

She made her Los Angeles Philharmonic debut under John Adams and premiered Katherine Balch's orchestral song cycle Illuminate with the California Symphony. Her performances as Lupita and Renata in the mariachi opera Cruzar la Cara de la Luna earned her praise as "brilliant" and "exquisite."
