Free jazz has not produced many notable guitarists. Experimental musicians drawn to the guitar have had few jazz role models; consequently, they've typically looked to rock-based players for inspiration. James "Blood" Ulmer is one of the few exceptions -- an outside guitarist who has forged a style based largely on the traditions of African-American vernacular music. Ulmer is an adherent of saxophonist/composer Ornette Coleman's vaguely defined Harmolodic theory, which essentially subverts jazz's harmonic component in favor of freely improvised, non-tonal, or quasi-modal counterpoint. Ulmer plays with a stuttering, vocalic attack; his lines are frequently texturally and chordally based, inflected with the accent of a soul-jazz tenor saxophonist. That's not to say his sound is untouched by the rock tradition -- the influence of Jimi Hendrix on Ulmer is strong -- but it's mixed with blues, funk, and free jazz elements. The resultant music is an expressive, hard-edged, loudly amplified hybrid that is, at its best, on a level with the finest of the Harmolodic school.
