Sometimes a video recording just seems to have it all and I would put the 2019 Salzburg Festival version of Verdi’s Simon Boccanegra in that category. It’s quite an interesting production but it’s the sheer quality of the music making that puts it in the very top bracket. It’s also technically very good in all departments.
Rossini’s last opera, Guillaume Tell, was written for Paris and is an extremely ambitious piece of great musical sophistication. It’s also very long. Performed uncut, a rarity, it runs something like four hours including ballets. It’s also hard to cast with the role of Arnold Melcthal in particular making unusual demands. It’s a high tenor role combining the flexibility needs of a typical Rossini role with something much more heroic. The soprano role of Mathilde has some of the same issues; signature Rossini coloratura is combined with the sort of dramatic heft one might more associate with early Wagner.
