Philly blossoms in May, and it really shows this week. Classical music and movie screenings are abundant this month, and CSz Philly’s Off the Recordis a musical mockumentary that will be unique each time it performs. ConsentFest from YES! sets up in Clark Park, and of course, there’s this week’s roundup featuring Theatre Horizon’s sandblasted, Masquerade from Koresh Dance Company, and Intercultural Journeys’ 20th anniversary celebration.
