esoteric as in inaccesible to layperson?
I do very much enjoy these elitist threads. yes it certainly is. Probly culminating in amon tobin, squarepusher, etc.
I think there is A LOT of accessible tunes though. RnB, Hip Hop, Ragga remixes are obviously accesible to those into those (un-junglized) sounds. Further to that the soulful vocally vibes (shake it, suicide, most MIST rmx's, carlito+addicition) are pretty easy to take. Sounds like pop music, just underground.
Up from that the latinny sounds and the weirder soulful stuff (total science, beta II, london elektricty) seem not that esoteric either. It definitely takes a slightly open mind b/c it is weird, but especially as a dj playing that in the context of a set you could definitely have non-heads into it.
So long as there is melody, you could appeal to non-DnB heads into other styles of electronic music. omni trio, mellow cert 18, metalheadz, some C4C, klute, juju, seems to go off on the dancefloor amongst those not at all into DnB.
Then it gets pretty esoteric i suppose. I wouldn' play Bad Co or Stakka Skynet for my brother (even though i'm always playing polar for him). And finally the IDM influenced DnB seems pretty weird to many junglists.
But certainly the most out there stuff ever is old skool DnB. Doc Scott - Dark Angel and much of the old metalheadz, formation, reinforced stuff is just too weird (and thats why i love it).
