The kaval and soprano sax take turns soloing and supporting each other, while the percussion supplies a sturdy rhythmic framework. There are also a few solos and duets that, along with great attention paid to dynamics, help keep the sound varied and interesting. In its more peaceful moments this reminds me a little of Codona, the old Don Cherry-Collin Walcott project. Then the musicians turn up the heat and could be mistaken for an Art Ensemble of Chicago offshoot. But the approach taken here is a melding rather than a juxtaposition, with the jazz elements logically flowing from the Bulgarian roots, and as such is one of the more successful folk-jazz fusions I've heard in some time.
