Though it's never business as usual at the Berkeley Symphony Orchestra, it's been even less so since the search began for a new music director. This week's tryout is Hugh Wolff, an innovative conductor whose work with the Saint Paul Chamber Orchestra and Frankfurt Radio Symphony Orchestra has earned a host of accolades. The program is yummy: the West Coast premiere of "Overture in Feet and Meters" by Aaron Jay Kernis; OsvaldoGolijov's "Night of the Flying Horses," and Dmitri Shostakovich's "From Jewish Poetry," both sung in Yiddish by current and former San Francisco Opera Adler Fellows; and, from the token non-Jewish composer, Ludwig Van Beethoven's Symphony No. 7. On Thursday, Feb. 21, at UC Berkeley's Zellerbach Hall (Bancroft Way at Telegraph Ave.). 8 p.m., $60, $40, $20 for students. BerkeleySymphony.org or 510-841-2800.
