Tonight sees Avery Amereau and Ben Bliss debut with The Cleveland Orchestra and conductor Franz Welser-Möst in the first of four performances of Mozart’s Requiem. For contralto Avery Amereau, the Cleveland appearance is one of a handful of debuts this season; next month she sings Das Paradies und die Peri with the Czech Philharmonic Orchestra and Daniel Harding, and July brings her debut with the Orquestra Simfònica de Barcelona i Nacional de Catalunya singing the Mozart Requiem conducted by Trevor Pinnock. In North America, she has given multiple concert performances this season. Last month she joined forces with Les Violons du Roy and Music Director Jonathan Cohen for Handel’s Alcina alongside Askonas Holt soloists Lucy Crowe and Kayleigh Decker. This was Avery’s second appearance with the French-Canadian chamber orchestra this season, having joined them for a concert of Bach cantatas under the baton of Bernard Labadie in December. The year’s end also saw performances of Bach’s Christmas Oratorio with Orchestre symphonique de Montréal, and Handel’s Messiah with both the St Paul Chamber Orchestra and the Handel and Haydn Society alongside tenor Ben Bliss. Ben returns to Boston at the end of the month for Bach’s Easter Oratorio - again with the Handel and Haydn Society - but before that he heads to Pennsylvania to join the Pittsburgh Symphony Orchestra for another performance of the Requiem. The North American concerts follow his appearance last month with the Deutsches Symphonie-Orchester Berlin and Robin Ticciati, as well as his portrayal of Tamino in The Metropolitan Opera’s December production of The Magic Flute with conductor Duncan Ward. Ben returns to the Met in the spring as Don Ottavio in a new production of Don Giovanni conducted by Nathalie Stutzmann, with a cast that includes AH artists Andrea Carroll, Dmitry Belosselskiy and Alexander Tsymbalyuk.
