This week, we learned that Allen Toussaint died after performing at a concert Monday in Madrid. He was 77 years old. Toussaint had toured extensively since Hurricane Katrina, but he was, in many ways, a reluctant performer. He preferred his life behind the scenes in the studio — writing, producing, and arranging songs. A disciple of Professor Longhair, Toussaint seemed to understand what New Orleans music could do for the world.
