“With her engaging stage presence and her dramatic soprano, perfect for this role, she was convincing right from the start with her brash first appearance in the saloon. Her voice has everything you could wish for in a role like Minnie’s: a powerful soprano with a radiant high register and secure, not too sharp-sounding top notes, a warm middle register that is touching and able to express her feelings, whether it be during Bible study or when feeling sorry for some of the unfortunate, uprooted gold prospectors, or her bitter disappointment when she learns the true identity of Dick Johnson. She sang her two little arias in the first act, ‘Laggiù nel Soledad’ and ‘Io non son que una povera fanciulla’, with delicate phrasing. She sounded just as gentle in the duet scene with Johnson in the second act. By contrast, she was triumphant and combative during the life-and-death poker game with Sheriff Rance. The final scene, in which Minnie makes her big dramatic entrance and saves Dick Johnson from being lynched, also had something touching about it when she said goodbye to Sheriff Rance and the grieving gold diggers and disappeared with Johnson at the back of the stage, hopefully towards a future with a happy ending.”

[…] Anna Pirozzi has the perfect voice for the title role of Minnie: firm, secure, gripping, but also childishly dreamy when she sings about love and her desires. In this tough man’s world, there is little room for sentimentality. With firm high notes, Anna Pirozzi knows how to assert herself, even against the male ensemble and the orchestra, which trumps mightily at moments. This is clearly where she has her strengths, but she can also vocally fill the lyrical moments of the role with notes of yearning.” – Klassik Begeistert

“We appreciate the incomparable asset that a true dramatic Italian soprano represents here to truly savour the appearance of the composer who, for having tried new experiences on the other side of the world, has nevertheless retained his unique colouring. While the long duet in Act II with Dick Johnson (‘Perdonate…’ (…) ‘O, se sapeste’) is already magnificent and shows the musicality of the performer with her full voice, we move on to another dimension after the revelation of the stranger’s true identity, a dimension that Pirozzi can handle with ease, first when she violently sends him away. She is then absolutely impressive when, pistol in hand, she has to confront Rance, who is looking for the fugitive, and then during the astonishing and testing card game that ends Act II in apotheosis”[..]
