S-Tone Inc. is multi-instrumentalist jazz musician Stefano Tirone's main musical project. Originating from Milan, Italy, Tirone has been a professional musician for over twenty years. The first official S-tone Inc. recording was released in 1992 during the acid jazz era, a formative time for Tirone, who was heavily influenced by the combination of soul, jazz and Latin rhythms of the period. He started playing music in the early 1980s during the new wave period. He graduated in architecture from Politecnico di Milano university and currently alternates between the two pofessions of architect and musician, though he has reportedly given priority to the latter in more recent years.
