Wagner's tale of the struggle between spiritual and profane love, and of redemption through love, is given a radical visual update in Sebastian Baumgarten's controversial yet thought-provoking Bayreuth production. Joep van Lieshout's giant installation 'The Technocrat'; dominates the stage, its industrial interior giving credence to the idea that Tannhäuser is one big experiment and playing host to some magnificent performances, among them Torsten Kerl's robust interpretation of the title role and Camilla Nylund's wonderfully empathetic Elisabeth. Recorded live at the Bayreuth Festspiele, August 2014.

Since the 1990s, Christoph Marthaler and his congenial stage and costume designer Anna Viebrock have caused a sensation with highly musical and atmospheric productions of plays and operas. It was only a matter of time, then, before this directing team was also invited to the Bayreuth Festival. Marthaler's style of radical deceleration proved ideally suited to Wagner's Tristan und Isolde in this production – with Viebrock's sober yet poetic sets – unveiled in 2005. In the 2009 revival documented here, Robert Dean Smith and Iréne Theorin were joined in the title roles by Robert Holl, one of the great basses of his generation, who sang the role of King Marke.

Continuing its tradition of unearthing little-known 20th-century operas, the Bregenz Festival presented the first staged production of Polish-Russian composer Mieczysław Weinberg’s “The Passenger” in 2010. Written in 1967/68, the opera relates the chance meeting of a former concentration camp guard and one of her former inmates on an ocean liner years after the war.

This is one of the most enjoyable opera produced. The playful production by Paul Curran (Teatro Lirico di Cagliari [Sardinia]) has a wealth of clever touches, and the sets and costumes are lovely, whimsical, imaginative, and wonderfully captured. T The libretto for "Cherubin" (1905), an homage to Beaumarchais and da Ponte, takes up the story of the character Cherubino from Mozart's "Le nozze di Figaro" and shows him suffering his first great disappointment in love, his rejection by the courtesan/dancer Ensoleillad. All ends happily, however, as Cherubin finds his real destiny in Nina, a girl his own age. The story is tightly constructed, the text full of wit and humor in lighter moments and rapturous poetry in the love scenes, and the DVD's subtitles are expertly handled.
