Claudio Abbado, Yehudi Menuhin, Valery Gergiev – they all supported Friedrich Kleinhapl in his extraordinary way. Paul Tortelier was impressed by his „brilliant
technique and remarkable personality which merges with the cello – an ability which is only specific to the genuinely talented – like Friedrich Kleinhapl, who has something to reveal.” But then a life-threatening sickness – the turning point from virtuous beauty of sound and technical brilliance to his astonishing expressiveness.
Attila Csampai, Stereoplay-Magazine: „His magnificent Guadagnini suffers, moans and complains because with him, everything is soaked thoroughly through with fundamental emotions and intensity of life. This is how he puts us – with his powerful, coarse, chiseled tone – under the spell of an electrifying story-teller who prefers the essential, the uncomfortable and real to every embellishment.”
