ok i hear you now. see my post above this though.you're misunderstanding
it doesn't come from nothing
rather it exists only in the context of that which it is post-
so does jungle (or anything) in a which but: not self-consciously. initial jungle producers were organically drawing on a diverse range of influences.
whereas post-scenes are self-consciously defined only in relation to that which they are post-. they do in that sense suffer from a lack of eclecticism.
