The opening of Einav’s latest album is a bit deceptive, perhaps even intentionally: Opening track “1415” starts like a Jewish tune, even Hasidic. But the roots of the album are the imagination and open mind of the saxophonist. Einav doesn’t play freestyle jazz, but there’s a lot of freedom in his jazz. The framework refuses to remain rigid. The improvisation, as opposed to most of the other albums reviewed here, is not organized according to a clear harmonic structure that repeats itself, but has a more fluid and even capricious regularity.
