Christian Wolff at 80

Roulette put on several shows in honor of composer Christian Wolff's 80th birthday, last year. But before this member of the 1960s New York School turns 81, the venue is squeezing in one last celebratory hurrah (with a cast of supporting musicians that includes Joey Baron and Nate Wooley). The bill includes a percussion duo piece, selections from Wolff's series of charming Exercises, and other recent works.
