Logan Richardson, Cerebral Flow (Fresh Sound New Talent). A twenty-seven-year-old Kansas Citian now living in New York, Richardson is an alto and soprano saxophonist with a song-like approach to improvisation, even at his edgiest. He and his equally adventurous quintet colleagues sustain interest through their interaction on ten pieces Richardson composed or, in the cases of “Animated Concept of Being” and “Free the Blues,” conjured as urgent pas de deux for himself and drummers Nasheet Waits and Thomas Crane. His “Urban Folk Song” is a highlight. Vibraphonist Mike Pinto, guitarist Mike Moreno and bassist Matthew Brewer, like Richardson representatives of New York’s yeasty new downtown jazz scene, function more as equal partners than as sidemen.
