The Jazz Greenfield: The Test Came Back¶
The Pattern¶
The previous essay on this lane, five days ago, closed on a specific, falsifiable proposal: rate Head Hunters before acquiring anything new, because "Chameleon" was "the cheapest, closest test available" of whether the organ-combo/groove-first hypothesis actually held. That essay was written when Herbie Hancock had zero rated tracks. The test has since been run. Herbie Hancock now sits at 7 rated, 3.43 mean — 4 tracks on Head Hunters (3.50 mean) and 3 on Future Shock (3.33). And the specific prediction landed: "Chameleon" rates 4 stars, alongside "Rockit" and "Watermelon Man." The essay's own proposed test came back positive. Worth saying plainly, because a essay that names a falsifiable prediction and then gets it confirmed is a rarer and more useful thing than a essay that just describes a pattern after the fact.
The other flagged gap has also closed. Curtis Mayfield's self-titled Curtis is now fully rated — 8 of 8 tracks — bringing his total to 13 rated, 3.15 mean. Both discipline items the previous essay named as owed before any new acquisition are done.
What the completed ratings actually show¶
Head Hunters landing at 3.50 rather than a clean 4.0 is itself informative, not just a confirmation. The hypothesis was groove-first, demonstration-averse listening; Head Hunters is a genuinely more virtuosic, harmonically adventurous record than the organ-combo tradition the previous essay pointed toward — closer to jazz-fusion proper than to Jimmy Smith's three-chord groove records. A 3.50 mean reads as "the groove-first hypothesis holds, with a discount for the record's more demonstrative moments" rather than either a clean confirmation or a rejection. Future Shock, Hancock's mid-1980s electro-funk pivot ("Rockit" is the one everyone knows), rating at 3.33 across a smaller sample suggests the pattern generalises past the 1970s into Hancock's later, more electronic period too — worth watching as he accumulates more ratings.
Curtis Mayfield settling at 3.15 across the fully-rated Curtis is a genuinely lower number than the profile's confirmed 4.0-cluster (Withers, Gaye, Sade). That's a real, useful correction to the previous essay's implicit assumption that closing the Curtis gap would simply confirm the existing pattern — instead it shows the lane's floor is lower than its ceiling, and that Mayfield specifically, despite obvious surface adjacency to the confirmed pillars, isn't landing as cleanly as Withers or Gaye. Worth distinguishing rather than folding into the same bucket.
The Recordings¶
Otis Redding, unchanged since the last check: 8 rated, 3.62 mean, entirely on (1966) Otis Blue — "Respect," "A Change Is Gonna Come," and "My Girl" all at 4 stars. Strong positive signal, still below the 10-rating confidence threshold, still worth letting accumulate organically rather than forcing a session.
Quantic: 10 rated, 3.70 mean — crossed the confidence threshold. 5th Exotic (9 rated, 3.67) is the substantial sample; a single compilation cut rates 4.00. This is now a confirmed lane artist by the model's own standard.
Jazzanova, flagged in the taste profile as needing a re-rate because an earlier 2.29 mean "is likely wrong": now sits at 6 rated, 2.83 mean — Of All the Things (3 rated, 3.33) holding up better than The Remixes 1997-2000 (3 rated, 2.33). The re-rate happened and the number moved, but not all the way into positive-signal territory. This reads as resolved-but-modest rather than resolved-and-confirmed: worth updating the taste profile's flagged-as-likely-wrong note to reflect the new, still-middling number, rather than leaving the old flag standing.
What's Missing¶
The previous essay already queued Roy Ayers, Donald Byrd, Lonnie Liston Smith, and the CTI/Blue-Note vibraphone-and-flute wing, plus the organ-combo tradition (Jimmy Smith, Richard "Groove" Holmes, Big John Patton). Re-checked two of those against the current full artist list rather than assuming the prior essay's check still holds: Roy Ayers and Lonnie Liston Smith remain genuinely absent. Donald Byrd is present — per earlier session notes, 6 of 7 tracks already imported on one key album, so not a fresh acquisition target, a rating-completion one.
### Acquisition Targets
- **Roy Ayers — Everybody Loves the Sunshine** (1976) — genuinely
absent; the vibraphone-and-groove CTI/Blue-Note wing the previous
essay queued, now with a positive Hancock test result to justify it
- **Lonnie Liston Smith — Expansions** (1975) — genuinely absent; the
spiritual-jazz-meets-groove register that sits closest to the
Alice Coltrane devotional thread already confirmed at 4.0 in this lane
