The first act of Die Walküre is among the most frequently performed fragments from Wagner's Ring. Taped live in Vienna in 2007, this latest version adds Franz Welser-Möst's name to the distinguished list of conductors – from Bruno Walter to Otto Klemperer – who have recorded it separately. Once past a curiously low-key account of the opening storm, Welser-Möst settles into an urgent if lyrical reading, capped by a sensual account of the great love scene. Johan Botha is the ardent if lightweight Siegmund, Nina Stemme his neurotic-sounding, declamatory Sieglinde. The real vocal honours, though, go to Ain Anger's superbly characterised Hunding – no bully boy, but a man who masks possessive resentment beneath a chilling mask of politeness. Along with his performance in Tannhäuser at this year's Proms, it marks him out as one of the great Wagner basses of our time.
