It’s perhaps surprising that Lalo’s Le Roi d’Ys isn’t performed much more often than it is. Most people probably only know it for the tenor aria Vainement, ma bien-aimée which crops up from time to time in recitals and competitions. Sure, it’s not strikingly original. The plot is a love triangle with overlays of revenge and divine retribution and the music is, with the exception of the rather fine overture, a bit on the rumpty tumpty side. But, let’s face it, there are plenty of standard repertoire works with implausible romantic plots and banal, if tuneful, music. I think there’s a large section of the opera audience that would very much enjoy this piece.
