I rather like recordings from the Macerata Festival where the performances take place in the enormous amphitheatre of the Arena Sferisterio. Bellini’s Norma is a good choice for such as setting and the 2016 production directed by Luigi di Gangi and Ugo Giacomazzi makes good use of the space. It also uses string. The sets are stringy. The very scruffy Gauls wear shapeless tunics with lots of string over them. The slightly smarter Romans also wear string. And everybody plays with string. There are more strings than in the Princeton Physics Department. There’s lots of face paint too. The production also makes use of a spectacular multi-coloured lighting plot but, apart from the visuals, is pretty conventional and straightforward.
Adelaide di Borgogna is one of those rather odd “serious” Rossini works where bel canto collides with opera seria. The plot is fairly accurately based on an episode from 10th century history and is most definitely not a comedy. The form has progressed well beyond a succession of da capo arias with multiple ensemble numbers and quite a few choruses. But there’s a throwback to an earlier tradition in the use of high voices for heroic male roles though it seems that by 1817 castrati were rather rare and the crucial role of Ottone, the German emperor, was from the beginning sung by a female contralto.
