Sorry if I'm posting a track that got already posted on one of the 40+ pages of posts.
Just dropping some tracks (not necessarily my favourites), from very different periods, which I define myself as "real Trance" (obviously they are part of one of the multiple sub-genres I won't risk myself to use or even name!). Obviously each period has it's own variation of Trance. Might have been easier to name this topic "authentic/original Trance" instead of "real". I understand the original poster wanted some "underground" tracks but I'm focused on the "real trance" part here (again from my point of view)
