This 2019-20 season, in her house debut with Opera San Jose as Ida in Die Fledermaus, Ms. Leslie was singled out by Opera Today for “[making] the most of her brief moments as she showed off her bright, pure soprano.” She made her solo debut with the San Francisco Symphony in their holiday concert ‘Twas the Night, was also slated to appear with the Symphony as the soprano solo in Bach’s Magnificat (now postponed due to COVID-19). In the summer of 2019 she toured Finland, Latvia, Estonia, and Sweden as the soprano solo in Brahms' Requiem and performed a recital of arias with Symphonia Caritas in San Francisco’s War Memorial Veterans Building. In her reprise as Josephine (HMS Pinafore) with San Francisco’s Lamplighters Music Theatre in August 2019, she was lauded as “sparkling…by turns lovelorn, impish and imperious.” She also re-joined the San Francisco Opera Guild’s outreach as Mabel (Pirates of Penzance). She returned to the Western Region Finals in the Met National Council Auditions in January 2020, garnering a third regional Encouragement Award. In Spring 2020, she was to debut with Merced Symphony as the soprano solo in Beethoven’s Symphony No.9 and re-join Pocket Opera as the heroine in a rare production of Wagner’s early opera Das Liebesverbot (both appearances postponed due to COVID-19). She is featured in conductor Ming Luke’s 2020 TED-Ed video “The Physics of Opera Singing.”
