Surprised that great Oliver Nelson record isn’t mentioned. A warhorse to be sure, but to me, at the level of Kind of Blue.
I think the reason that the old recordings can sound so good is manifold:
- the studio equipment was far more primitive, less outboard gear, less fiddling with tracks;
- the musicians were extremely capable- they could play the whole song in a single take, even stuff that had orchestrated parts; no "oh, we’ll fix it later" mentality.
I do have a lot of the warhorses, but lost interest. My interest was renewed a little over a decade ago. I got into so-called "spiritual" and "soul" jazz through the recommendation of someone I knew. There were a few labels that concentrated on this-- mostly top notch sidemen who had no work on mainstream records in the post-Monterrey "youth" explosion. Perry Como was out; new sounds were in, thanks to people like Chris Blackwell at Island who signed an amazing roster of talent (Traffic, Crimson, Free, Tull, Fairport Convention, John Martyn, eventually Bob Marley, etc.)
Meanwhile, in the "jazz" world, it became much more local, community oriented stuff- in NY, Detroit (Motown moved to the West Coast), the West Coast sound, including all the acolytes of Horace Tapscott. Nate Morgan was a killer pianist who did stuff for Chaka Khan when he wasn’t doing deep jazz.
I’m only scratching the surface here, but to paraphrase David Lindley (RIP), the brilliant string player, you can make almost any song "jazz" (Lindley said "reggae" but I think it’s all the same).
If you like straight ahead stuff, check Art Pepper’s last recording of Patricia (he released it three times), this last version, with Cecil McBee (one of the most tuneful bassists I’ve ever heard), Roy Haynes and the recently departed Stanley Cowell (co-founder of Strata-East, one of the wellsprings of spiritual jazz). It is accessible and McBee’s bass work is classic, as is Cowell’s piano work. Pepper was a great altoist:
