Strong cast Amongst a uniformly strong cast, certain performers nevertheless stood out. Lyric baritone Brett Polegato anchored the opera with a convincing performance as Tell while tenor Jesús León as Arnold deftly negotiated the difficulties of Rossini’s most fearsome tenor role even if his French was perhaps not the most idiomatic.

If the opera is arguably about the hero, its most demanding role goes to Arnold with its stratospherically high bel canto notes and dramatic weight needed throughout.

He grew into his role too, the chemistry between him and Mathilde increasing over the acts.
