"The renowned artist played Mozart's concerto KV 414 beautifully sparkling and with an extraordinary warmth of touch." (Bertrand Boesch, Sierre) "Chumachenco is not only the outstanding interpreter of his own transcription, which is as knowledgeable as it is virtuoso, but he also opens up new, fascinating perspectives on a work's architecture that has never been seen before (...) in its basic aesthetic patterns in such a way could "look at" sensitively." (GP, FonoForum 4/93 on "Carmina Burana") "A pianist of a special, personal character, whose playing is characterized by exceptional sensitivity. The (...) 4 mazurkas op. 33 by Chopin conveyed wonderful poetry." (FvApell, Bad Lauterberg) "The lightness of Chumachenco's playing, his brilliance and the subtle virtuosity, which broke ground both in the cadence of the first movement and in the realization of the concluding variation movement, seemed like pianistic manifestations of that bright, wild and extraterrestrial laughter, which Hermann Hesse attributes to the composer in "Steppenwolf." (T. Janssen, Elbe-Jeetzel-Zeitung Feb. 2004 regarding the Mozart concerto KV 453 in Hitzacker/Elbe with the Virtuosi Saxoniae under Ludwig Güttler)
