The authoritative Corriere della Sera critic and musicologist Paolo Isotta wrote of Nicolosi on the occasion of the recent 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-century works, 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.
His recordings include works of Thalberg, Mozart (complete piano variations), Rachmaninoff, Clara Schumann, Scarlatti, and Paisiello (complete piano concertos). Nicolosi's website provides a complete list.
