One of seven adaptations of Mozart’s late masterpieces and part of the In Series 2009-2010 season, this 2003 English adaptation of Cosi Fan Tutte, a tale about women tricked into betraying their fiancés, was re-imagined and set in 1929 Hollywood by Nick Olcott. This is one of three “pocket operas” this season, so called because they’re being staged in such a small space. Opens Saturday, Sept. 12. Running through Sept. 26, in partial repertory with From U Street to the Cotton Club. Source, 1835 14th St. NW. Tickets $31 to $38. Call 202-204-7763 or visit www.inseries.org.
