"Recording of the month: They're both electrifying, and they sound absolutely magnificent ... Pappano makes sure [the Fourth] sings as often as it can ... This is a terrible beauty, energetic, Satanic, utterly spellbinding, keeping enough in reserve to make the biggest climaxes truly shattering ... The opening bars of this Sixth, a cry of anguish that's also passionate bel canto song, promise the very best recording of the work".
