When the most voluptuous, sought-after courtesan in the world meets an ascetic monk whose life is devoted to God, you know erotic sparks are going to fly. And when the clash takes place in a glorious, but rarely performed, opera by Massenet, it’s a delight to the ear just as much as to the eye. Renée Fleming is every inch the glamorous Thaïs, swathed in elegant gowns designed by Christian Lacroix. Thomas Hampson is Athanaël, the tortured man of God. This production by John Cox, which premiered in December 2008, brilliantly sets the stage for a confrontation as old as civilization itself.

The story of the conversion of the beautiful courtesan, and the clash between spirituality and sensuality have been portrayed brilliantly by Pier Luigi Pizzi, one of today’s most talented opera directors. The visual quality of this production is indeed one of its strong points, and the DVD recording will not fail to fascinate the viewer.

There's an uncompromising clarity to Blu-ray audio and video that really does bring the splendour of grand opera right into the living room. So it's all the more frustrating to get a compromised production as the final product. Jules Massenet's 1894 tragedy about a sex goddess humbled by an insistent Cenobite monk isn't produced very often, because of a demanding lead role and some difficult staging issues. But the music is gorgeous from beginning to end. When you have a great diva at centre stage, the three acts go by in a flash.
