Singers are inherently interesting, I suppose, and the talk has been mainly about Bejun Mehta's last-minute substitution for David Daniels. But the counter-tenor wasn't really the main event in this superb evening of seventeenth-century Italian chamber music. The Arcadian Academy, Elizabeth Blumenstock, Lisa Weiss (violins), Phoebe Carrai (cello), and David Tayler (lute), all members of Nicholas McGegan's Philharmonia Baroque Orchestra, delivered the diverse programme in style. The performance began with a manic bravura bergamesque by Uccellini and an expressively singing dialogue for violins by Salamone Rossi. The big fellas showed why they were big: Corelli's Ciaconna detta La Virginia was pure pleasure, and a suite by Nicola Mattei, based in England for most of his slightly dodgy life, had echoes of Purcell and a punchy selection of styles and forms that looked forward to Rameau. Bejun's substitution of three Handel arias for one of the Scarlatti cantatas ruptured the time frame, but actually made a sort of sense by highlighting Handel's profound debt to Italian instrumental composition, especially Corelli. It was a well considered selection as well, two heroic arias (Up the dreadful steep ascending, from Jephtha, and Empio, diro, from Giulio Cesare) with Verdi prati in between. Mehta showed a wonderful grasp of the form of the arias, the way Handel makes the voice into an instrument, using the techniques that Corelli and Mattei use to make the instrument into a voice, and achieving a near perfect combination of form and expressiveness. The surviving cantata, Perche tacete, regolati concenti, is explicitly a kind of dramatic symphony, with the voice as the solo instrument in a sequence of short movements. The text is a commonplace meditation on the pleasures and pains of love, with the usual imagery of music and war thrown in. The whole thing is addressed to a beloved who ignores it, and provides the opportunity for a self-absorbed virtuoso performance, which again Mehta delivered, contrasting anger and despair and ending in masochistic resignation. He even gave an "ah" of contentment as he finished. Mehta probably got lucky by being available for this tour, because McGegan's dramatic and technical understanding of this music seems to suit him perfectly. He was obviously more at home in Handel than Scarlatti, which he has only just learned, but he can do the music -- the notes, the drama, the lyricism -- wonderfully in both. Mehta looks a little bit like the young James Bowman, and his precision and exuberance are also somewhat similar. His voice is close to the traditional Anglican sound, very unlike David Daniels', but he produces it far more easily than anyone except perhaps Michael Chance, and (perhaps a generational thing) he's got far more natural expressiveness and sense of drama than Chance. The high point of Mehta's performance was probably Verdi prati (mysteriously missing from Daniels' Handel CD). Apart from maybe Scherza infida, this is the richest and most allusive of all Handel's opera arias. Mehta's singing really made me think about it again. It sits at the centre of concentric circles of illusion, disillusion and loss in a way which is almost unstagable. Rinaldo finally realises that he can't incorporate Bradamante into the dreamworld of Alcina's island, that she's come to take him away, to marriage, to his heroic career but also (he dimly realises) to death. As the realisation sinks in, instead of longing for his home and real life, he mourns the illusory world he is about to lose, trying to explain his loss as part of the cycle of nature, but returning to the finality of the destruction of Alcina's artifice. The effect is ironic and prematurely romantic at the same time -- Rinaldo really doesn't know what he is losing -- in one of Handel's most understated but expressive settings. Mehta got the tone of melancholy, with something much more profound behind it, perfectly, with pianissimo's to raise the hair on the back of the neck. There were some noises off during the concert, but there were plenty of fireworks indoors tonight as well.
