AVA reclaims Verdi's first opera

The overture promises Verdi at his more dire - Rigoletto, only bloodier.

And then his first-ever opera, the rarely performed Oberto, written in 1839 when the composer was 26, unfolds like a manifesto of operatic revisionism. The past is touched upon and the future is predicted in the concert version presented Thursday by the Academy of Vocal Arts at the Kimmel Center's Perelman Theater.

The plot doesn't amount to much: Another strong-minded heroine named Leonora confronts another faithless seducer named Riccardo. At least Oberto doesn't pretend to be about anything real, as does Verdi's later (and inferior) Attila. And none of the score's experiments - the chamber-music-like sections in the overture - go down blind alleys, like the quasi-violin concerto in I Lombardi.

In fact, the first act of Oberto could be Verdi in any period but his last. The musical language and the dramaturgical instincts are all there. The act's finale is a bravura feat of operatic pacing: It has three climaxes, so effective that many composers would be hard-pressed to top any one of them. The only deficit is hit tunes, though in a performance as terrific as Thursday's, you might not notice.

The second act, full of bel canto formulae, sounds as if it was written first, with limpid accompanying ostinatos that become more twisted and dramatically eloquent. The ending threatens to fizzle, though AVA's music director Christofer Macatsoris - the primary hero in this feat of operatic reclamation - would never let that happen. Nor would the dramatically adept star Michelle Johnson (Leonora). When she vows to take the veil in Oberto, there's no doubt she'll be the angriest nun in the convent. Is that dramatically accurate? In such a visceral opera as this, there's only one rule: Is it effective? And it was.

Johnson displayed all the Leontyne Priceian tone of past performances, but she also sang with more meticulous accuracy. Early Verdi operas have roles requiring everything: Sopranos must have a mezzo-ish lower range and nicely floated high notes, and be card-carrying coloraturas. That last aspect has been Johnson's weak link, but on Thursday you might not have known it.
