BBC music magazine2015 DecemberafafBerta Joncus2015 December"Vurdering: BBC music opera choice" - "There is perhaps no singer better able to meet this challenge than Swedish mezzo-soprano Ann Hallenberg: her rich timbre, the evenness of her register and the precision of her intonation evoke Marchesi's vocal qualities convincingly. She delivers cadenzas and diminutions with careless ease".

Ann Hallenberg's powers of supple precision, melodic sweetness, flawless coloratura and expressive pathos are on compelling form".
