"Musical delight - In the pit, Alejo Pérez emphasises the smallest details of this demanding and complex score. He delicately sculpts the motifs, makes the architecture perfectly legible - and takes the sound material in his hands to make it more than just a backdrop for the voices: an additional character that enters into dialogue with them."
Diapason Magazine, Anne Ibos-Augé, 3 June 2025, (Wozzeck, Opera Vlaanderen)
"The visually austere directorial concept allows the music to come to the fore, and you don't have to tell conductor Alejo Pérez twice. Wozzeck is a milestone of expressionist musical theatre and one of the first operas to flirt so explicitly with the limits of tonality. Berg uses extreme dynamics, abrupt silences, screeching contrasts and a tonal language full of abrasive dissonances to bring Wozzeck's psychosis and hopelessness to life. This is where the Argentine conductor goes full steam ahead: the blistering orchestral tension builds culminate in a finale that leaves no soul untouched."
Opernwelt, Lotte Thaler, 18 July 2025 (Wozzeck, Opera Vlaanderen)
"Berg's uncompromising masterpiece remains a sledgehammer blow even today. Simons and Pérez make it a mad show - in every sense of the word."
De Standaard, Bram van Haelter, 2 June 2025, (Wozzeck, Opera Vlaanderen)
“And you have to take your hat off to the Argentinian conductor Alejo Pérez, who lightens up the textures in this monumental work to form a remarkably fluid orchestral framework and soak it with a dramatic tension that never lets down.”
Crescendo-Magazine, Paul-André Demierre, 28 March 2025, (Khovantchina, Grand Theatre de Geneve)
"Alejo Pérez succeeds in shaping Strauss's score transparently despite its massiveness. Where the opera is almost falling apart and the composer pours out his virtuoso, Bavarian-style self-assurance, Alejo Pérez also gives the monkey sugar and lets the musicians of the Symfonisch Orkest let off steam with vigour and delight, but in between, the musical partners repeatedly find a rhetorically well-founded, distinct chamber tone and transform the virile, lusciousness of the musical text into delicate, finely-nerved eloquence."
Opernwelt, Jürgen Otten, February 2025, (Salome, Opera Vlaanderen)
"...The Sächsische Staatskapelle under Argentinian guest conductor Alejo Perez gives the evening great, exciting brilliance. A blooming, glowing cosmos of sound that captivates from the first bar."
Michael Ernst, MDR Klassik, 29 April 2024 (Káťa Kabanová, Semperoper Dresden)
“We’re in particularly safe hands musically. Alejo Pérez conducts without artifice and presents Stravinsky’s music in all its honesty. Argentinian by birth and serving at the Flemish Opera since 2019, Pérez is a breath of fresh air in the way he approaches the composer’s early works. Avoiding artifice, he conducts with pure naturalness and grace. An enthused, spirited Adelaide Symphony Orchestra follow with their usual high degree of accomplishment.”
InReview, Graham Strahle, 2/3/2024 (The Nightingale and Other Fables, Adelaide Festival)
“The Orkest Opera Ballet Vlaanderen was terrific. Alejo Perez’s baton was absolutely in time with the youthful exuberance of this production: daring flourishes of fortepiano in the recitatives, electrifying articulation in the strings, the ‘mafia funeral’ moments for the trumpets – those heralds of Verdi – and, of course, there was pure clarinet seduction.”
bachtrack.com, Eleanor Knight, 12/9/2023 (La Clemenza di Tito, Opera Vlaanderen)
“Pérez succeeds in giving a large ensemble the sound and energy usually found in smaller ensembles.”
forumopera.com, Maxime de Brogniez, 21/9/2023 (La Clemenza di Tito, Opera Vlaanderen)
“Conductor Alejo Pérez has the orchestra striving and yearning, swirling with passion and endlessly tender singing especially in Tristan’s death scene and Isolde’s Love Death.”
KLARA, Sylvia Broeckaert, 23/3/2023 (Tristan und Isolde, Opera Vlaanderen)
“The music then becomes the key word of the performance, first and foremost through the direction of Alejo Pérez. His intense reading of the work (…) is greeted with a standing ovation by the audience.”
Forum Opera, Christophe Rizoud, 26/3/2023 (Tristan und Isolde, Opera Vlaanderen)
“The production is carried out by an impeccable cast, supported by Alejo Pérez’ scalpel-precise direction, which highlights the score’s modernity, its power, its formal and orchestral richness, and its lyricism, leaving the audience overwhelmed by its power at the end.”
Avant Scène Opera, Alfred Caron, 9/9/2022 (Aufstieg und Fall der Stadt Mahagonny, Opera Vlaanderen)
“Alejo Pérez on the podium of the brilliant Orchestre de la Suisse Romande ingeniously implements Bieito's concept with the means of conducting dialectics. The Argentinean subtly traces the ambiguity of the score. Prokofiev proves to be much more subtle in his alienation than his colleague Shostakovich. Whoever says yes (especially in the overwhelming chorus parts) may very well mean no. For all the lavishness of the music-making, Alejo Pérez twists and turns the staves, discovers in all the sensitively played out nuances what a great complex score Prokofiev has left us here.”
Opernwelt, Peter Krause, November 2021 (War and Peace, Grand Théâtre de Genève)
“Alejo Pérez, remarkably efficient, alert to every feeling, revealing tenderness as well as murderous madness, an unparalleled creator and lover of sound, is particularly at ease in this musical element.”
letemps.ch, Sylvie Bonier, 16/9/2021 (War and Peace, Grand Théâtre de Genève)
“The crispness and elegance of Alejo Pérez’ conducting style are combined with the kind of inspiring imaginative ability an orchestra needs to test and transcend its boundaries.”
Die Welt, Peter Krause, 21/3/2018
“More relaxed and joyful than in the Strauss, the Vienna Philharmonic and the highly-talented Alejo Pérez created a wonderful sound, treading the fine line between penetrating pathos and sentiment without becoming sweet or sensationalist. In Marguerite’s great scene, the conductor and orchestra sparkled. A great achievement.”
Online Musik Magazin, Thomas Tillmann, 20/8/2016
“From Wagner’s opulence to the soft backlight of impressionism, from veristic emotional outbursts to seditiously expressionistic opalescence: under the direction of the magician Alejo Pérez who can turn frogs into princes, the orchestra of l’Opéra de Lyon brought Schreker’s visions to life.”
Le Monde, 17/3/2015 (The Stigmatised)
