I must confess, I'm not that familiar with the New Orleans scene (definitely have to look into it some more though) but The Meters have a slight Curtis Mayfield vibe who I absolutely love. If you haven't heard the Superfly soundtrack I highly recommend it.
An album cut! I'll look forward to it.
Nah, I think the Meters really invented the fusion between NOLA second-line drumming (among other techniques) and traditional funk from up north. Before then, it was a lot of regional hits, combined with standouts like Fats Domino and the select few who went nationwide, and Lee Dorsey and all the great singers who used more traditional R&B/rock and roll arrangements.
And the people who used studios and session players since time immemorial like Ray Charles and so many others.
Anyway, I wouldn't even NOLA has
one sound: like they say, it's more of a mixture. Maybe some of the countrified music, from Zydeco to Jelly Roll Morton stick to some specific genre, more or less loosely, depending.
Anyway, I'm not a scholar of NOLA music, it's just one of those profound influences I couldn't get away from if I tried, and I'm not even from there, although certainly have some distant cousins down in Cajun land of whom I'm unaware and vice versa.
I think the "scene" down there from hearsay is quite a bit a different from the 1950s-1970s, especially when a lot of iconic players moved to Los Angeles and did a bunch of session work, at least temporarily. Much more modern, hip sounds, but always with an eye to the past, using the keyboards and the horns when desirable.
