Guest conductor Teodor Currentzis — who boasts he will save classical music in a 2005 Daily Telegraph interview — appears with the SSO this weekend in a mildly interesting program. The all Russian program which features Aram Khachaturian’s jagged violin concerto and the evergreen Fifth Symphony of Shostakovich should test the conductor’s mettle to make the banal (Khachaturian) and familiar (Shostakovich) interesting. The American Handel Festival continues performances of the Dixit Dominus, Bach’s St. John Passion, and an organ concert at St. Mark’s Cathedral. More information on all of these concerts is available at the festival website. Seattle Pro Musica even has a short video preview of their Dixit Dominus concerts this weekend.
