Anne's recent concert highlights include bicoastal performances of the Beethoven Triple Concerto with the Venice Symphony in Florida under the baton of Maestro Imre Palló, and with One Found Sound Chamber Orchestra in San Francisco. Last summer Anne performed as a fellow at Yale’s Norfolk Chamber Music Festival, collaborating with faculty and student composers.

Currently pursuing her DMA at UCLA with Grammy Award-winning cellist Antonio Lysy, Anne is a member of VEM Quartet, UCLA’s string quartet-in-residence. Anne’s past performances brought her to many prestigious venues, including the Kennedy Center, the American Cathedral in Paris, Rolston Recital Hall at the Banff Centre, the Britten Studio at Aldeburgh Music in the UK, and the Bing Concert Hall at Stanford University. This year Anne performs the Shostakovich Concerto with the UCLA Symphony. Anne has performed with symphonies in past seasons including the Sonoma County Philharmonic, the Knox-Galesburg Symphony, the Quincy Symphony, and the Southeast Iowa Symphony. 


Classical Sonoma wrote of Anne’s performance of Rococo Variations, “The delightful top-to-bottom slides on the fingerboard were impeccable, and in the cadenza Ms. Suda never hurried, letting the long pauses add suspense to the music. She clearly identified with the subtle and non-heroic interplay of cello and orchestra.” Anne has been praised for bringing a fresh and contemporary sound to her repertoire, with the Northwest Reverb writing of her interpretation of the Debussy Cello Sonata, “Cellist Anne Suda read so much contrast into the score, intermittently I felt I wasn't hearing Debussy at all, but discovering his lost contemporary genius…it was the freshest interpretation I’ve heard.”


Passionate about chamber music, Anne is a founding member of two award-winning ensembles. With Anne’s contemporary chamber group Nonsemble 6, she performs an original staged and memorized production of Schoenberg’s Pierrot lunaire throughout the country, receiving a grant from SF Friends of Chamber Music to fund the project. Her ensemble Aleron Trio was in-residence at Britten-Pears, Aldeburgh Music in England and at the Banff Centre in Canada. In addition to performing three tours of France, Aleron Trio won the 2014 Barbara Fritz Chamber Music Award and served as Ensemble-in-Residence for the Old First Concert Series in San Francisco.

Anne also recently adjudicated at the California Senior String division MTNA competition at UC Santa Barbara.

She received her Master of Music degree from the San Francisco Conservatory of Music as a student of Jennifer Culp of the Kronos Quartet, studied at the Sydney Conservatorium, and received her Bachelor of Music degree from Vanderbilt University where she double majored in English Literature.
