"His success and the special attention attracted by his performances prove Jánoška’s unique talent. Extraordinary technical dispositions and independence of his performing of the most challenging pieces as well as the charismatic expressivity of his playing inspire spontaneous admiration in his listeners. His domain for now are Romantic composers – their musicality and challenging interpretation. Jánoška has been very successful also at interpreting 20th and 21st century opuses."
