Well it gets even more confusing here in Sweden, were "Forest Trance/Scandinavian Forest Trance?" or whatever they call it is popular as well. Also very dark, perhaps more intensely shroomy/organic/trippy? I think this labeling has become a bit redundant, as most of this could fit under the same umbrella, namely a darker form of Psytrance/Dark Psy/music for the night sets/Twilight music/whatever. :) The people at the party sure as hell don't know that the tracks played on the same night/in the same set are "different subgenres". It's all night music, darker in the mood, some darker than others, but hey that's just variation at play, which is inevitable. It's not like there is a degree system/scale for how dark the music should be in order to pertain to any of these subgenres.
I think what this is about really is slight geographical differences/touches to the same genre (Dark Psy). Which has then for some unknown reason been labeled as different subgenres. It's like before when we within the old school Goa Trance scene had, "UK Goa Trance" Israeli Psytrance/Goa Trance" "Swedish Goa Trance" "Italian Goa Trance" etc. Very different in style for sure at times, but surely belonging to the same genre. And made even more confusing due to how it was marketed. For example many of the acts we today categorize as Goa Trance from the UK, was marketed as Psy Trance, simply because the term Goa Trance had fallen out of fashion.
I also think the music will be labeled according to what record label it was released on, "oh it was released on that label" then it must be yadayada, because they focus on yadayada.
I'm almost getting the impression that the artists don't want be associated with the older term Dark Psy? And that the newer subgenres are more in vogue, hence more suitable to be associated with? Like a marketing hype/buzz word. So what happened with Dark Psy and Dark Full On? Did those genres cease to exist when people changed their preference/style description of the subgenre they identify with and the scene/scenes they participate in? For example I remember that Goa Gil was a household DJ name first with Goa Trance, then with Dark Psy. What does he play/promote today? Any of the above genres? Or maybe he quit, I have no clue. Perhaps it became to confusing with the subgenre-nitpicking.
I have this scenario playing in my head while reflecting upon this topic. I Imagine some party people arriving at a forest/outdoors party here in Sweden, and asking either where the Techno floor is, or where the Psytrance floor is. Okey they'll be guided in the appropriate direction, and upon reaching the Psytrance floor, the psy fan might say hmm this is too cheesy, it's full-on! I want darker music. OK just hold on, the next DJ will play that in an hour. I don't think it matters then if the DJ plays Twilight, Dark-Psy, Forest Trance, British Psytrance, or South African Psytrance. The person will most likely be satisfied with the dark music on offer, unless the person is a psynews forum member that is. Then the PDF shared here will be taken out, and the style identified and classified accordingly. So therefore I think this interchangeable labeling/terminology is quite unnecessary for most people attending these parties.
