Engelbert Humperdinck: Hansel and Gretel: Staging directors Patrice Caurier and Moshe Leiser infuse German composer Engelbert Humperdinck's fairy-tale opera with more than a dollop of black humor in this 2008 London performance that's both enchanting and menacing. Angelika Kirchschlager and Diana Damrau play Hansel and Gretel, respectively, and beloved British baritone Thomas Allen portrays their father in an outstanding production led by maestro Colin Davis.
