Jazz musicians don't have hit records. Some even consider it sacrilegious. But Ronny Jordan, the London-born, New York-resident guitarist did, with a 1992 acid-jazz version of Miles Davis' famous So What. But Jordan is now celebrating his jazz roots, delivering a lightly swinging set of straightahead jazz, devoted to departed guitar heroes such as Wes Montgomery and Grant Green.

The other half of the bill is occupied by a powerful local quartet led by the Coltranesque British saxophonist Alan Skidmore - who also performs heartfelt tributes to a hero, but with more abrasive energy than Jordan. The guitarist has respectfully absorbed those qualities of Wes Montgomery's sound - the thick, glowing chords and mellow octave slides - that also brought hit-making smooth-jazz status to Montgomery in the 1960s, but without that improvisor's capacity for inexhaustible spontaneous melody. Jordan solos run out of steam unless the groove is insistent enough for him to operate in a more percussive manner, bouncing clipped motifs off the beat.

On his opening remake of a Wes Montgomery staple, Mister Walker, Jordan caught the original's softly surging swing, and pianist Rob Bargad played the first of several effectively understated breaks over Wayne Batche lor's robust bassline. Jordan's earthier Grant Green side came out on D Natural Blues, but the Thad Jones ballad A Child is Born turned into too few fresh melodies to work much beyond its elegant theme. Grant Green's gospel-like Sunday Mornin' was a different story, with Jordan on home turf, volleying holy-rolling phrases at a rejuvenated rhythm section, and on the warmly greeted So What, the groove similarly shook loose the guitarist's powers of invention. That was plenty enough for Jordan's many UK fans.
