I have friends like that as well... They can't even tell the difference between the music i make myself and Astral projection That means one of these to things:
1: They are def
2: They don't care about the music, and don't listen to anything ells than the kick/bass rythm(typical for people who only like the music when they are high, drunk and wants to dance)
But psytrance shouldn't be to hard to descripe: Wierd soundeffects, blurry riffs you can't figure out what melody/tones it is, its just good sounding noises Maybe some psychedelic melodies.. lots of layers of different elements making the soundpicture more "thick" than regular trance. It isn't build on a surtain theme that keeps on comming back in the track, but instead theres a story(normally that is) Darker heavier basslines, faster bpm (over 140) The kick is often alot more punchy
Progressive trance: Another genre wich tells a story instead of running on the basic melody, then break, then melody again wich ends in a qlimax. It progresses, evolves, really calm (130-140bpm) adds stuff, changes stuff, drags you into the track, without any big melodies. Instead it (normally) has lots of layers, supportive synths for the basslines, lots of percussion and... Well just a more chilled feeling than the other trance genres.
Darkpsy: If theres any doubt here, the idiot shouldn't be aloved to listen to trance
That's it for me, i don't listen much to goa trance anymore, so i won't try to descripe that
