Here's an excerpt, to whet your...axe.
"The jewels in this performance’s crown were the two queens: soprano Ellie Dehn as Catherine of Aragon and mezzo Jennifer Holloway as Anne Boleyn. Dehn began as an icy presence, but that facade cracked as the reality of her situation became apparent. She achieved dramatic heights in the final act, with a long aria that recalled the plight of another operatic queen in a similar circumstance: Elisabeth de Valois in Verdi's Don Carlos. "
