"...Tellefsen spun out a transfixing melodic line. His sound was rich and beautifully colored, with sufficient litheness to save it from schmaltz; but most impressive were the patience and assurance with which he shaped the course of his monologue, carefully charting its crests and gathering its long span into a single unified utterance. 
Tellefsen´s fiery execution of the mammoth cadenza was gripping, and he tore into the ensuing Burlesca with winning vitality".

"Tellefsen proved an extraordinary patrician and resourceful interpreter.
He exhibits a pointed sound, amazing facility in passagework and the flair to dispatch the cadenza without shrinking from its demands.
The performance seemed organically wrought, with every measure contributing one stone to a grand edifice".

"Tellefsen´s playing is seemingly effortless. He picks out every slight phrase, not just the melody biggies, making a deeper sense of the work. His projection was penetrating, even on the deeper notes of ascending scalic passages with full orchestra. This, coupled with his troppo trilling and light vibrato, was very attractive.
He phrases concisely without clipping and made the solo line sound like a sublime voice".
