I just finished String Quartet No 2, Quattro Canzoni Degli Umori (four tunes of the humors). Perhaps I shouldn't be so quick to say it's finished as there is still some cleanup and notational issues to deal with. Still, for the most part, it's finished, done, complete and nearly ready for performance.
Which is a good thing since I hope to have it in my recital coming up on October 12th. The piece is only 15 mins in length and packed with intensity.
Program notes and a midi realization of the music is available at the above link.
