Maria Stuarda, Landestheater Schleswig-Holstein

Maria Stuarda’s adversary, the Queen of England, has a fitting performer in Julia Mintzer. Her Elisabetta is bursting with anger, frustration, arrogance and self doubt— frames of mind and characteristics which the American, with her full, earthy, powerful mezzo-soprano, is able to capably realise with her expressions and her voice. —Das Opernglass, January 2017

Julia Mintzer acted in the role of Elisabetta as a gloriously bitchy power-house and wicked dominatrix with a bronzed mezzo sound.   — Flensburger Tageblatt, January 2017

Carmen, Landestheater Schleswig-Holstein

The American Julia Mintzer, a guest, is ideal casting: fresh, lascivious, coquettish, and strong. Her soprano register shines like fire, while her mezzo register definitely shows that she is not to be trifled with.        — Kieler Nachrichten, September 2016

Julia Mintzer plays her role with cynicism, innocence, and cruelty, barefoot at the beginning, and with great dedication, She is very seductive with her body language and her acting. Her voice is especially expressive in her high register.    —Schleswiger Nachrichten, September 2016

Carmen, Boheme Opera New Jersey

As Carmen, mezzo-soprano Julia Mintzer took immediate command of the stage and the role. From her opening "Habanera," Ms. Mintzer was clearly a cut above the singers heard to that point in the opera, and she never came onstage without sultriness and vocal craftiness.  Her scenes with tenor Patrick Miller's Don José were among the most dramatic in the opera.      —Town Topics Newspaper, April 2016

Madama Butterfly, Florentine Opera

Mezzo-soprano Julia Mintzer was wonderful as Suzuki.  Her voice was rich and pliable-- from chest-tone power in the lower range to a graceful floating quality in her higher range to a flexible ability to blend with Cambridge in their gorgeous Flower Duet-- and she brought a quiet dignity to her role.    —, October 2015

Julia Mintzer (Suzuki) and Mark Walters (Sharpless), by contrast, powerfully embodied their roles, both dramatically and musically.                        —, October 2015

Orfeo, Grand Harmonie

Der Teufel mit den Drei Goldenen Haaren, Die Semperoper Dresden

Ariadne auf Naxos, Die Semperoper Dresden 

Equally impressive was a fine female trio of Naiad, Dryad, and Echo: Emily Dorn, Julia Mintzer, and Arantza Ezenarro. Their fabulous costumes were matched by assured singing and acting, offering quite the model of an Ariadne performance.                                                                           —, April 2014
