"At the podium of the Münchner Rundfunkorchester (which absolutely surpassed itself that night), with the excellent choir of the Bamberger Symphoniker and an inspired cast that presented a flawless performance in every role, Marcello Viotti had a truly great moment, exceeding even the most daring expectations. Of course: Viotti has conducted all of Bellini’s operas, his "Puritani" at the State Opera were exemplary; he conducted "Norma" in various different productions. Viotti conveys Bellini’s articulation of phrases, even the style of the - not always comfortable - stabs of the violins. He has polished even the smallest details with his singers. But how from all this effort result such perfect balance and movement, without Viotti having to set more than the necessary tempo, is an almost breathtaking dramatic achievement. Bellini’s line of music remains embedded in a many-faceted network of signs, but at the same time unfolds from each individual moment. A Belcanto sound drive that never seems squashed or inflated, maybe last seen in this form with Carlos Kleiber. Michael Gielen’s much-praised "Norma" in Berlin was purely classicist-rhetorical in a continuation of Gluck. In the Callas interpretation, “Norma” was purely romantic-psychological, in the belcanto tradition from Sutherland to Gruberova purely Victorian-idyllic. But Viotti shows us: Down to the smallest detail, "Norma" is all of these things."
