If you want to know what else it says about a-j:
"The phrase was the first jazz term to be coined by a DJ rather than a
musician.It is much more a marketing phenomenon than a coherent musical
style even more so than "trad" and as with trad, acid- jazz is very much the
commercialisation of a revival movement.Just like earlier revivals,it was
inspired initially by listening to records rather than live musicians.In
this case,the original style is that of late-60's and early 70's jazz funk
but was more jazz-orientated than the average soul record.At first,this
found a ready response among black listeners and a few white aficionadoes
and than ,after the usual 20 year gap,a new generation of aficionadoes
succeeded in promoting the music to a much wider crossover audience."
