While it's far from a great record, something about this June 1962 session -- first issued as LP #1 of the HIPGNOSIS set, then on its own in Japan, then as a bonus session tacked onto the domestic reissue of VERTIGO -- has always stuck with me. The vibe of it is rather 50s Jackie, but, of course, here he's still working out the consequences of his decisions to go more outside on LET FREEDOM RING (March 1962, but not released until almost a year later). The re's something comfortable about the music; I'll credit the presence of the Clark-Warren-Higgins rhythm section. But there's also a tension, too.
IMO, some of that tension is a byproduct of KD's own tightrope walk between bop orthodoxy and the more expressionistic approach he started exploring as early as the 2 HORNS / 2 RHYTHM date with Ernie Henry. Maybe his chops were starting to go, as many have observed, but I'd like to think most of the hallmarks of his early 60s approach were the result of a deliberate choice on his part to further explore the possibilities of both his instrument -- a la Don Cherry -- and a more purely melodic and rhythmic approach to solo construction.
Case in point: the variations he spins on the Warren-composed head throughout his solo here. In some ways, his entire solo is simply a recapitulation of that initial statement, with subtle alterations of timbre, inflection, cadence and register. I would never claim this as KD's "Impressions", but there's something about his working over of motifs here that recalls Trane and Rollins. And I love that moment at just after the 3-minute mark where the shape of the descending phrase he plays recalls -- for me anyway -- someone sadly shaking their head at the what can't or won't be resolved. Anyway, it's a solo I find fascinating from a "generative constraint" point of view.
