I'm mostly surprised that a post about psytrance gets over 400 upvotes on HN. I'm a former (goa/psy) trance producer (in another life and century), and recently coming back to the world of producing. Maybe I'm stuck in the 90s, but it still feels to me like that "underground" sound we dance in the forest or desert to. But nope - 400+ upvotes on HN means it's a lot less underground than it is in my head, and even though the millennium was just "2 years ago" it seems like there was a lot of progress in those "couple years".
