There's an interesting thing I'd stickle against though;
So OK, if jungle/drum & bass revisitation and re-enactment is meant to be like say, the Rockabilly Revival, this doesn't work really because there's still a pre-existing Drum & Bass scene culture that's gone on to it's present day incarnation. Albeit, one that probably lacks the 'purity' of the original (the same way EDM-ready dubstep is a diff. beast to its origins) but has traces and continued practitioners from those earlier incarnations. Rockabilly Revival bands emerged to regenerate a lack, because it'd been long outmoded and the scene didn't exist as it once did (if at all really).
So in the case of Drum & Bass you have it's initial scene, then the scene of the tasteful revivalists doing it in a modern form (your Special Requests and all that) who keep it seperate from that larger scene. These are two dance cultures with two differing levels of participation, engagement, dancing etc. Then you've got the sort of soundcloud Old-Skool Jungle/darkcore/hardcore artists I know blissblogger often posts about on his blogs in which, are those even engaging in either scene? Or do they just half-live on the net as a community that celebrates itself without transposing itself into the physical world less its construction not hold up in the proper context of being dance music (something that ultimately defines all Rockabilly Revival because it's primarily dance music, even in the rock context).
stickle is a good word!
it's not an exact analogy but i think it works
you have the original rockabilly / fifties rock'n'roll, which evolves into Sixties beat music, then into psych, then into various early 70s forms prog / heavy metal / glam, then into punk, then into etc etc. it's all rock music - guitars, bass, drums - and it carries on evolving, shifting, expanding, contracting again - but there's a line there back to Chuck Berry etc
but then at a certain point you start to get rock'n'roll revivalists fixating on this early phase of explosive teen wildness / innocence, and associated stylistic tropes (quiffs etc etc), trying to bring it back to life, or just stay there in that golden moment forever
i mentioned Polecats and Stray Cats, i.e. outfits after punk, but there were r'n'r revivalists going back as early as 1968-70 - Shakin' Stevens actually started in the early 70s, playing Communist Party dances in Wales!... you also had high-profile figures like Lennon saying there's been nothing better than Jerry Lee Lewis and Little Richard, making his music more raw and simple, then doing his r'n'r covers album.
with ardkore, you have a similar trajectory - starts chaotic, raw, primitive, often made by teenagers... gets more sophisticated / heavier - and taken seriously by your bourgeoisie just like with rock'n'roll in the Sixties - it goes through various phases and permutations - one branch of it keeps shifting and evolving (UKG etc)- and another (drum and bass) gets fairly fixed and narrowed in focus (i would compare that to the heavy metal line out of rock'n'roll, with Bad Company as Motorhead)
but meanwhile you have figures popping up fixated on the earlier primal innocence, or doing little fun excursions into the nostalgia zone
the first one i noticed was Jega - out of that Mike Paradinas cluster - who in 1998 did a fun facsimile of the Noise Factory type sound called "Card Hore"
so that is six years after the fact, a slightly accelerated original era >>> nostalgia process, but not that much faster than with Fifties rock'n'roll which starts to get retro remakes and nostalgia nods in 1968 with Zappa's doowop project, Beatles' "Back in the USSR", the Move's "Fire Brigade" with its Duane Eddy lick - so that's like a 10 to 12 year interval.
late Seventies rockabilly revival was a dance-driven thing, you are right there - it blew up around the same time as the ska revival and mod revival - when there was a demand for some high-energy fun sounds after punk
i should imagine some of the producers making homages to hardcore or jungle are trying to make tracks that would get a crowd moving, and perhaps there are djs doing whole sets in that vein, i don't know - but there's others where it's more like a ghostly echo 'revenant rave' thing they are doing, and it exists mostly on the internet.
