The second CD of Il Tetraone is dedicated to the two fortepiano quartets K478 and K493 by W.A.Mozart, played on period instruments by the four members of the Accademia Bizantina. Ottavio Dantone wrote: Il Tetraone was born within an ideal "great quartet" like the Accademia Bizantina, combining its philosophy and closing a perfect circle in the most genuinely chamber music form.
