"The Deutsche Oper Berlin is an important Wagner house, once dubbed "the winter Bayreuth" ... Before the music begins, across the stage troop a group of migrants who later serve as contributors to the action as Nibelungs or observers, as in a Greek tragedy ... Herheim is also aware that this is in Berlin, and there are some World War Two and Wehrmacht references, about which he is quite unapologetic ... Derek Welton and Annika Schlicht, have impressive voices well suited to their roles ... The Brünnhilde of Nina Stemme and Siegfried of Clay Hilley bring the same qualities heard in Siegfried ... Runnicles and the Orchestra of the Deutsche Oper Berlin are superb throughout, as is the chorus (in Götterdämmerung) ... The filming and surround sound are excellent ... Mainly in the highly eloquent singing and playing, you will find much to impress, question, debate and decode in the innovative production".
