In 2018, I met up with Tyshawn Sorey at the Guggenheim Museum in New York for an interview that involved me playing a series of records for him and soliciting his thoughts. We listened to everything from Anthony Braxton, Roscoe Mitchell, and Eric Dolphy to Metallica, Redman, and Autechre. And at one point, after listening to a recording of Eric Dolphy's "Jim Crow," a piece that was more 20th century classical than "jazz," we discussed something that has plagued jazz musicians for almost a century: the respective roles of composition and improvisation.
