A Greek miracle at the Orchestre Symphonique de Québec..
From Debussy’s ‘Prelude, L’Apres-Midi d’un Faun, the conductor stood out with a slow but precise, economical gesture, allowing the various strands of the orchestra to unfold quietly… Grammenos was impeccable here, as he was later, in the orchestral main course, Stravinsky’s 1919 Firebird Suite. Again in this latter work, Grammenos brings out absolutely incredible colours, from the first bars of the score through to the Berceuse. The interpretation, of great flexibility, could perhaps seem a little too romantic to some ears, but it demonstrates how much the work has a strong foothold in the 19th Century. This boy is destined for great things in all probability. We hope to see him again soon on the same stage.
Emmanuel Bernier, Le Soleil

The young guest conductor of Greek origin, Dionysis Grammenos, took charge of the OSQ with great mastery. His sobriety, precision and efficiency provided a beautiful shape to the orchestra. He really committed to the music!
Jacques Leclerc, Les ArtsZe

This is one of the best Bohèmes I have heard in recent years… Anyone who has heard Beecham or Karajan’s recordings of Bohème will know that, like all great opera, the starting point is an exceptional conductor. Here we get one with the Greek clarinettist Dionysis Grammenos, whose command of Puccini’s idiom is impressive.
David Mellor, The Daily Mail

… the sparer forces found a more concentrated wiry intensity in the music, spurred on by remarkably crisp conducting from Dionysis Grammenos, who excelled in focusing the rhythmic energies of the score. Seldom in London has that treacherous opening downbeat, with its wafer-thin semiquaver rest, burst forth with such control and promise. Grammenos has thrown a gauntlet down to the other major pit orchestras in London who frequently revive this bread-and-butter work.
Benjamin Poore, OperaWire

Really gorgeously conducted by Dionysis Grammenos with acute sensitivity to the emotional flow
Robert Thicknesse, Opera Magazine

In the pit, conductor Dionysis Grammenos draws animated, richly coloured playing from the 27- strong orchestra, providing plenty of Puccinian perfume and punch, but a welcome clarity and freshness too.
Claire Seymour, The Stage

Puccini’s way of sweeping the listener straight up with youthful high spirits, wistfulness and the bustle of Bohemian Paris can render much else redundant. Dionysis Grammenos’ firm and flexible conducting establishes that clear enough.
John Allison, The Telegraph

Under conductor Dionysis Grammenos the orchestra achieves a pleasing transparency while not skimping on the occasional blatancy that Puccini demands.
Nick Kimberley, Evening Standard

In the pit Dionysis Grammenos gave us a lithe and engaging account of the score. Grammenos zipped along, and the dialogue flowed beautifully. This was very much Puccini as heightened dialogue, rather than a series of set pieces arias, and it worked very well indeed.
Robert Hugill, Planet Hugill

The orchestra is expertly handled by conductor Dionysis Grammenos. The music is truly moving, underscoring the emotion played out on the stage.
Rebecca Armstrong, Opera for All

Dionysis Grammenos came to my attention as an extremely talented young Greek conductor, already quite experienced in both opera and concert. He has an analytic mind in conceiving scores and a very profound way of expression. He can convey these qualities with great charisma!
Christoph Eschenbach, Music Director designate Konzerthausorchester Berlin

Mr Grammenos has proven to me his extraordinary abilities as a conductor, and he has distinguished himself in a highly competitive field. He is unquestionably an artist of unusual ability.
Patrick Summers, Artistic & Music Director Houston Grand Opera

Dionysis is a marvellous clarinet player. I heard him at the Eurovision Music Competition where we were so impressed with him, we gave him first prize. He has fine technique, excellent musicianship and pleasure to hear.
Sir Roger Norrington, Eurovision Young Musicians Competition President of the Jury

His boundless, instinctively poised and naturally unfolding musicality as well as his impressive technical command of the métier apply for his acclaimed clarinet playing as well as his conducting. You find in him a musician who exudes an enthusiasm for music from every single pore and who equally has the talent to communicate and share his enthusiasm and euphoria with others – no matter if it’s about an audience or fellow musicians.
Johannes Debus, Music Director  Canadian Opera Company

Dionysis Grammenos is a phenomenon in music, among these that come along once in a rare while. Tremendously talented and gifted with extraordinary musicality.
Theodor Antoniou, Composer, Maestro, Prof. Boston University

One of the most promising Stars of tomorrow.
Die Welt (Nov. 2013)

A child prodigy! (Ein wunderkind!)
Daniel Stabrawa, 1st Concertmaster of the Berliner Philharmoniker

One of the most important clarinetists of our day.
Michael Guttman, Violinist, Conductor

He is a major talent. His natural affinity on the podium is very rare, and his musicianship is extremely refined.
Larry Rachleff,  Music Director Rhode Island Philharmonic, Walter Kris Hubert Professor of Music Rice University

I was struck immediately by his playing and the reaction of audiences. His virtuosity is stunning, and his musicianship and phrasing is natural, communicative, and engaging for audiences. He has an engaging personality, and audiences love his charisma and charm.
Paul Keene, Barbican Classical Music Programming Director

He really is something special…he sounds extraordinary. World class !
Rex Richardson, Trumpet Soloist/Jazz Artist/Composer, Yamaha Artist

Dionysis Grammenos is an artist full of vitality, vitality that is so important to the world of classical music.
Christian Lindberg, trombonist, composer, conductor

This also undoubtedly applies to the 21 year old clarinetist Dionysis Grammenos. He won admiration through the rich interchanges, the velvet interpretation. The quintet of Carl Maria von Weber in B major gave him the opportunity to show his considerable artistic skills, which he admirably placed at the service of the composition. The “dance” passage was performed with exceptional elasticity and with a delicate musical sound. His performance was impressive with rich confident musical phrasing, the warm and dark colours of the trills but also with the exact placement of the rhythmic pulse. Although only 21 years of age this greek musician already has a remarkable interpretive capabilty and an astonishing feeling of style. The enthusiasm of the audience was obvious!
