Born in Siena, Azzolino Della Ciaia was an italian organist, harpsichordist, composer and organ builder. He worked as an expert organ builder and most notably worked on the organ of Santo Stefano dei Cavalieri, a large 5-manual and more than 60 stop organ. Mara Fanelli and Olimpio Medori bring Ciaia's works to life with their rich musicianship.
