The authoritative critic and musicologist Paolo Isotta has written of him on the occasion of the recording of two rare concerts of Paisiello: (...) listening to him playing is enough to remind us that no one today can match his luminosity of sound, his ability to draw out the song-like legato qualities of a keyboard instrument (...) he has acquired a reputation as one of our greatest living pianists (...) The great Arturo Benedetti Michelangeli performed eighteenth-centuryworks, his inspiration came principally from the same source as Nicolosi’s, but perhaps lacked some of the latter’s lucidity and coherence. Nicolosi is now perfecting the process begun by Michelangeli.
