"The enthusiastic eloquence of these readings is attributable to the internally radiant tone, the carefully yet never pedantically articulated 'vocalisation' of the music and the sensitively breathing lines which never allow the beautiful sound to become an end unto itself, rather one means of expression alongside the contrariness of plucked strings and an almost percussive attack (second movement of Busoni's Sonata)." FRANKFURTER ALLGEMEINE ZEITUNG
"Alois Kottmann is a master of bowing technique. He extracts every last drop of music from Busoni's Sonata and Messian's Théme et variations and turns the Brahms Sonata into a magnificent song. The interplay between the two instruments is perfectly balanced." DARMSTÄDTER ECHO
"The Busoni Sonata, a concert-hall rarity, is a unique work of its kind, a strange mixture of temperament, brooding intensity and the fantastic. The duo impressively delineate the dramatic arc of this monumental composition in this intelligent interpretation." FRANKFURTER ALLGEMEINE ZEITUNG
