A concert celebrating rebirth and renewal through the music of Claude Debussy, Béla Bartôk and Igor Stravinsky. Join Circadian as we take you back in time to the year 1909, a year that Ford’s Model T cost $850.00, tensions were escalating on the Serbian border with Hungary, and nationalism was on the rise leading eventually to the First World War. San Francisco at this time was being rebuilt after the 1906 earthquake. In Europe, Debussy was the acknowledged leader of the avant garde and two upstart young composers who felt his influence were making their mark. The 28 year-old Béla Bartôk premiered his first string quartet which combined the harmony of Debussy, the counterpoint of J.S. Bach and the bracing rhythmic vitality of the folk music of his native Hungary. Meanwhile, the young, unknown 27 year-old Russian composer, Igor Stravinsky rocketed to fame with the premiere of the Firebird, his first full length ballet composed for the Ballet Russe in 1909 and premiered in 1910. Circadian celebrates this truly transformative time with the world premiere of our own reimagining of Stravinsky’s Firebird, arranged for string quartet, piano and percussion by our very own David Ryther, three piano preludes exuding the magic of Claude Debussy transformed for String quartet and Béla Bartôk’s ground-breaking String Quartet No.1 provide rich context for the renaissance of ideas swirling around in 1909. Our exciting guests artists include violinist Roseminna Watson and pianist Keisuke Nakagoshi, this is a program not to miss!

Bay Area based Circadian String Quartet was founded in 2013 to promote the classical and contemporary string quartet repertoire, in particular music of cultural and folkloric significance. Since then, the group has been featured through Mt. Shasta’s Music By the Mountain, Sunset Music | Arts Chamber Music Series in San Francisco, and the Merced Symphony Association. In 2014, the CSQ were invited to collaborate with the St. Petersburg-based Rimsky Korsakov String Quartet during their North American tour. They have also given U.S. premieres of pieces by world-renowned British composer Ian Venables in collaboration with mezzo-soprano Sally Munro of the San Francisco Opera and Natalie Parker, Principal Clarinetist of the San Francisco Ballet.

David Ryther (violin) has brought his interpretive powers as a soloist to such festivals as the Darmstadt Summer Festival of New Music, the Banff center, and the Green Umbrella Series at the Bing theater in Los Angeles. He has been featured playing new music with adventurous ensembles sfSoundGroup, Earplay, San Francisco Contemporary Players, the Berkeley New Music Ensemble, Sonor, and Octagon. He is a founding member of the Presidio String Quartet, a group that specializes in contemporary music. David graduated with highest honors in music from UC Santa Cruz and recently received his doctorate in contemporary violin performance from UC San Diego. David can also be found playing in the Berkeley Symphony, the San Francisco Ballet orchestra and teaching violin at the Crowden School for Music.

Roseminna McLeod Watson (violin) began work on the violin at the age of three, and one year later finally acknowledged her need for some help with the endeavor. Her mother, Clyde Watson, taught her for the following six years until she went on to study at the New England Conservatory’s Preparatory School with Melba Sandberg and Magdalena Richter. Ms. Watson holds a B.A. in Graphic Design from Yale University, a Masters in Violin Performance from Stony Brook University and an Artist’s Diploma in Chamber Music from San Francisco Conservatory of Music. She has had the opportunity to collaborate in performance with many renowned artists including Menahem Pressler, Natasha Brofsky, Jean-Michel Fonteneau, Axel Strauss, Paul Hersh, David Tanenbaum, Jennifer Culp, Jodi Levitz and Donald Weilerstein. Her primary teachers include Clyde Watson, Melba Sandberg, Magdalena Richter, Syoko Aki, Soovin Kim, Ani Kavafian, Pamela Frank, Ian Swensen, and Mark Sokol.

Ms. Watson is the former first violinist of the Aiana String Quartet, winners of the 2011 String Prize at the Coleman International Chamber Music Competition. From 2011-2013, the ensemble was the Young Professional String Quartet in Residence at the Butler School of Music at UT Austin under the mentorship of the Miró Quartet. Since Aiana’s amicable dissolution in 2013, Ms. Watson has been rebalancing her energy and continuing her life-long exploration of multiple expressive disciplines — painting, writing, video, and composition. Her fascination with the human body as a vehicle that carries us closer to the divine is evident in her work across mediums. Roseminna currently performs as a solo-act multimedia artist / singer / songwriter / violinist, is a frequent collaborator with dancers, artists, and other musicians, and is a founding member of  Humming Owl — a duo with her singer /songwriter / sitarist husband, Pablo Escalante. Her first solo album, Limbic Hymnal (2017), is available at for physical copy, and on the iTunes store for digital download. Roseminna plays an Agostino De Plani Violin from 1779 and a commissioned bow by Benoit Rolland, 2015.

Native of Iran, Omid Assadi (viola) holds a B.M. and M.M. from San Francisco Conservatory of Music where he studied with Jodie Levitz and Bettina Mussumeli. Mr. Assadi is an active ensemble player and soloist; he has concertized with many of the Bay Area’s orchestras and has appeared numerous times as soloist with Golden Gate Philharmonic, City College of San Francisco String Orchestra, Kensington Symphony Orchestra, and Villa Sinfonia. Omid’s love for chamber music has led him to study chamber music with the members of the Kronos String Quartet as well as the San Francisco Conservatory of Music faculty members. In addition, he has collaborated with Jennifer Culp, Jodi Levitz, Jorja Fleezanis, and with the Shams Ensemble.

David Wishnia (cello) performs regularly with many orchestras and chamber ensembles throughout the San Francisco Bay Area.  He is a member of the Villa Piano Trio and the Circadian String Quartet.  He holds a Masters of Music in cello from the Yale School of Music.

Keisuke Nakagoshi (piano) has received training from some of the most celebrated musicians of our time – Emanuel Ax, Gilbert Kalish, Menahem Pressler and Paul Hersh and he has performed concert stages across the United States, including the Kennedy Center, Carnegie Hall, the Hollywood Bowl, and Davies Symphony Hall in San Francisco. In 2014, he made a solo debut with San Francisco Symphony on Ingvar Lidholm’s Poesis with Herbert Blomstedt conducting. In 2009, Keisuke and Swiss pianist Eva-Maria Zimmermann formed a piano duet team, ZOFO and their first CD was nominated for Grammy award for best chamber music/small ensemble in 2013. Aside from ZOFO, Mr. Nakagoshi is currently a pianist in residence at the San Francisco Conservatory of Music, and also he serves as pianist in the production team for Opera Parallèle.
