by Scott YanowThere is plenty of variety to the third album by the unique World Saxophone Quartet. The music ranges from nearly free improvisations to the four-part "Suite Music," which was almost completely written out. Rather than being a screamfest for the four innovative saxophonists (baritonist Hamiet Bluiett, altoists Julius Hemphill and Oliver Lake and tenor saxophonist David Murray, all of whom double on other reeds), this is a well constructed and sometimes surprisingly accessible (although always explorative) program.
