Mr. Andriessen’s music is carefully structured, strictly notated and technically demanding, yet he loves to improvise and is passionate about jazz. (Stan Kenton comes up regularly in interviews.) He says he is uninterested in pop and disdains the Beatles, but he quickly adds that he loves the Supremesand other Motown groups. And though he says he dislikesopera, at least in its traditional form, he has written five theater pieces that he calls operas.
The latest, “La Commedia” (2008), will be performed in a concert version at Carnegie Hall on April 15, the centerpiece of Mr. Andriessen’s Perspectives series at Carnegie Hall.
