This can be deceptive. I can recall the Chick Corea/Steve Kujala recording Voyage being criticized as being all written until Corea confirmed to me that it was virtually all improvised! In this case, it is fair to say that there is a lot of written material in these performances, but the relationship between written and improvised material is hard to determine.
Such considerations are, of course, irrelevant in the overall scheme of things, outside of a reviewers responsibility to convey some idea of the music. Suffice to say that the genre reflects the musician's declared backgrounds, a mixture of jazz, classical, and folk, with a fair dash of whimsy. The emphasis is on the mixture; the various influences are sublimated to an overall group sound, with the folk elements softening the more stark soundscapes normally associated with Free Jazz.
Several reviewers have mentioned that the group might sound better with a bass player. I tend to agree with them. The bass is such an important part of any jazz ensemble and I can imagine how someone like Gary Peacock or Dave Holland could add to the sound. As it is, Radley has to supply some bass lines as well as the harmonic textures, a tough trick when he is soloing. But that appears to be the group's choice. "Asked why they don't have a bass player," writes Barteldes, "Schneider just said that they began playing together and felt comfortable with the sound. ‘This is the band,' he told us."
Readers who enjoy the unconventional may well enjoy this recording.
