Performer: Edita Gruberová

Deutsche Oper's concert production of Norma shows what a great opera it is; Edita Gruberová displays great artistry, although now with imperfections.

Christof Loy's modern-dress production of Donizetti's Roberto Devereux for the Bayerische Staatsoper is deliciously, darkly ironic. A dream cast handles the dramatic and musical challenges well, though the voice of the star sounds worn for this star vehicle.

67-year-old diva Edita Gruberova presents a devastating portrayal of a desperate mother supported by a strong cast in a stark modern production.
