The plight of women trapped in plural marriage—one husband with multiple wives—glowed like a firebrand on the Perelman Theater stage on Sunday. Opera Company of Philadelphia’s Dark Sisters, in co-production with Gotham Chamber Opera and the Music-Theatre Group, is OCP’s final offering of the 2011-12 season.
