The December Quartets

I went to The Harrison on Saturday night to see The December Quartets. It is a tiny venue with a capacity of about 45. It was an incredible evening full of beautiful improvisation. Spyros Giasafakis is one of the members of the quartet. They improvise using vocals and very unusual instruments. It was a night to remember.
