Cavalli’s Il Giasone is a bit of a rarity but perhaps, like the rest of his opus, it’s getting more attention than it used to. The latest video recording of it was made at the Grand Theâte Genève in 2017. There’s a summary of the rather convoluted plot in my review of an earlier version from Vlaamse Opera. Oddly in this version Isifile’s final aria omits the weird section about her cold dead breasts.
Cavalli is a rather neglected composer. Something like thirty of his operas exist but few are ever performed and only one, La Calisto, appears at all frequently. It’s hard to see why. He was Monteverdi’s pupil and a worthy successor whose work was decidedly popular in his lifetime. It’s even harder to see why a work like Elena could have been ignored for 350 years before being revived at the Aix en Provence Festival in 2013. It’s really got the same things going for it as Il coronazione di Poppea. There’s sex, homoeroticism, mythology, cross dressing, a weird (Shakespearean?) mix of the serious and the comic and some really lovely music. The only downside I can see is a rather convoluted plot and the fact that one of the leading roles was written for a high castrato.
