Improvisation here refers not only to the music, but also to the film itself. Humbert and Penzel state in the 2003 DVD release of the filmThe film is not narrated, and the musicians, the music and the locations are not identified. Instead it is a sequence of snapshots taken of Frith and musicians he has worked with, rehearsing and performing, interspersed with apparent random images of movement trains, cars, people, grass that blend in with the music. The improvised nature of the film and its Direct Cinema approach make it more of an art film than simply a documentary on a musician. ........
