“[…] Sladek proves to be a master of scatting!” JAZZTHING, 2021

“By singing only vowels, Sladek frees himself and his listeners from the constraints of unambiguous language, allowing room for impressions, for feelings. […] The listeners are transformed here into the owners of a piece of art, shaped by their thoughts and uniquely retrievable only by them, like a dream.” SÜDDEUTSCHE ZEITUNG, 2022

“Anyone who hears ‘Syllabulism’ has no doubt about his talent anyway. All that remains is the wish to be able to experience Sladek’s great feeling for moods, climaxes, rhythms and interplay live again soon.” SÜDDEUTSCHE ZEITUNG, 2021

“There were also instances where the expertise of the musician and singer made you feel like you were leaving them behind in the distance. And then you felt like closing your eyes and imagining a butterfly, floating about over a field of pretty flowers in the mild breeze. This was accompanied with the pitter-patter of raindrops and the chirping of birds.”
DAWN, 2023

“He is an incredibly intuitive performer, packing sensational rhythms into his tongue-twisting syllable salad.” DONAUKURIER, 2022
