"The most essential element of his interpretation was the savouring of the dramatic at all levels. Even the main theme of the first movement [of Rachmaninov's 3rd Concerto] was not simple and plain but attained an unheard of voltage through the deployment of arresting accents, rubato and quasi improvisando playing. This intensity and concentrated awareness of the playing coursed like a red thread through all three movements."

“At the end you do not know what was more striking, the spiritual maturity of this slender young man or his inexhaustible, one might almost say abnormal physical force with which he hammers the staccato in the keys - a veritable hurricane unleashed - the agility of his fingers in the sparkling runs and arpeggios, the fantastically precise grip in the prestissimo chords or the quirky, picturesque phrasing with which Sgouros can freely express extra emotions.”

„Am Ende weiss man nicht, was mehr frappierte, die geistige Reife dieses schlanken Jünglings oder dessen schier unerschöpfliche, fast möchte man sagen abnorme physische Kraft, mit der er die Staccati in die Tasten hämmert und Orkans entfesselt, die Gelenkigkeit seiner Finger in den perlenden Läufen und Arpeggien, die traumhaft präzise Griffsicherheit in den Prestissimo-Akkordballungen oder die erregenden skurrilen, pittoresken Phrasierungsfloskeln, mit denen Sgouros zusätzliche Emotionen freiwerden lässt.“
