Mount Wilson Observatory’s “Sunday Afternoon Concerts in the Dome” presents “Piano Quartets” at Mount Wilson Observatory

Mount Wilson Observatory (MWO), Southern California’s esteemed home to several of the most groundbreaking astronomical discoveries in history, presents the final Sunday Afternoon Concerts in the Dome of its 2026 season, inside the magnificent vaulted dome of MWO’s historic 100-inch Telescope.

On Sunday, October 4, 2026, the audience is invited to experience "Piano Quartets," with musicians David Kaplan (piano), Ambroise Aubrun (violin), Ariana Solotoff (viola), and Cécilia Tsan (cello). The program will feature Mahler “Piano Quartet in A minor” and Brahms “Piano Quartet No. 3 in C minor, Op. 60.” For more information on this concert, please visit: www.mtwilson.edu/events/concert100426

For MWO’s final concert of the season, the recently acquired historic 1907 Steinway Model O grand piano in ebony (No. 125947) will take center stage. The piano was generously donated to Mount Wilson Observatory by Dr. James Vail, Professor Emeritus of Choral and Sacred Music at the University of Southern California. Following a restoration by Teri Meredyth—made possible through anonymous gifts—and a skilled move and install by P&O Movers, the piano made its debut at MWO in April, and has been featured throughout the 2026 concert season. As in previous seasons, Artistic Director Cécilia Tsan (Principal Cellist, Long Beach Symphony and Los Angeles Master Chorale) curates the series. Each concert date of the season features the same program presented twice—first at 3:00pm and again at 5:00pm. There will be an artist reception at 4:00pm between each concert’s hour-long session. Tickets cost $65 each and are available for purchase online.
