Featuring members of the San Francisco Symphony and the San Francisco Opera Orchestra, Trio della Rosa perform with guest violist Marcel Gemperli in a concert of chamber music that exploits the exotic scales and wild rhythms of Eastern European folk music, including Piano Trio in F minor by Arno Babajanian; Trio-Miniaturen by Paul Juon; and Piano Quartet No. 1, Op. 25 by Brahms.
