Your uniqueness lies in the touch. It is this touch that from your first steps into the world of music ensured the beauty and richness of the colors of your incomparable sound. The range of dynamics in each case from four “piano” to five “fortes” was so artistic, so caressing, and at the same time powerful compared to me with the force of a typhoon, but always beautiful, always with depth, the sound always natural in the service of ideas that the force of your very special talent puts you at the full service of the equally natural sensitivity of artistic ideas.”
Univ. Professor. Ilirjana Dema, Professor at the University of Arts in Albania
“Kosti tonight has given me an emotional load as rare times. Kosti has Solar energy and a Lunar pianissimo in the way he handles expression, a model of how the sonority can be relaxed up to 4 or 5 pianissimo. He played Bach, Mozart, Rachmaninov, Peci, and Liszt, meaning authors of different eras, different musical styles, and aesthetics. Kosti with a depth of thought that transcends the boundaries of his age and very good technical preparation decomposed the characters and styles traveling from one era to another as if he were a real acoustic – psychologist. He swam with an elegant pianissimo full of charm in a snow-white landscape of white keys, while sometimes a light breeze gently moved him to the extremes.
His GESTURAL CHOREOGRAPHY (a very important element for the performer) made the audience reward him with electrifying applause and many “bravo”. The Gestural choreography, the choreography of the gesture itself, and his whole body choreography in relation to maximizing the expression of thought and emotion deserve a full scientific conference. This is how much I appreciate this issue so much and how important I consider it. But Rachmaninov and Liszt’s Sonata were two peaks that the public conveyed with a lot of emotional charges. Liszt’s chords in Kosti’s hands have a meteoric energy, and they seem as if they are micro Asteroids in space that expload with Solar Energy which Kosti suddenly relaxes and transforms it into the coloring of a poetic rain of sounds. it really was a fantastic night.”

“Mr. Deti was a student at the Tartini Conservatory in Triest while I was Piano Professor there. He was not my pupil, but I had the opportunity to listen to him just in one occasion: nevertheless, the memory of his playing is still vivid to me. I immediately found he has a stunning personality and a natural propensity to establish a strong, empathic connection with the audience, being able to communicate a lot of emotions in a very magnetic way.”
Giuseppe Albanese
“…It was a wonderful concert. Kosti Deti is one of those talents that come rarely. With an extraordinary power to express emotion and to communicate deeply with the spectator. Kosti Deti achieves as rarely seen to communicate through the piano, easily challenging any kind of technical difficulty and speaking through the colors of sounds. His playing, full of passion, thought and temperament makes the spectator stay all the time captured by the magic of his sounds. It was truly a concert where Kosti Deti came opened and ready to enter the international interpretation circuit.”
Univ. Prof. Nora Cashku, Professor at the University of Arts in Albania
Kosti Deti has been named by Kostandin Bogino Jury Chairman (Russia) as “Albanian Volcano”, in Venice where Kosti was awarded the 1st prize in the international competition San Dona di Piave of the Alink Argerich Foundation

The words, employed even by literary masters, falls short in capturing the enchantment crafted by the talent, abundant imagination, magnetic prowess, artistic conceptualization, and virtuosity of this “alien.”

He unraveled the characters and styles, traversing from one era to another as if he were a true acoustico-psychologist. He swam with an elegant pianissimo full of charm in a snowy landscape of white keys, which occasionally a gentle breeze subtly shifted towards the extremes.
