 Characterized by having obscure, deep, and more eschatological background that leads into profound meditation of death, night, and transcendence, often with dismal sounds and heavy basslines.The subgenre often samples horror films in contrast to the science fiction film samples more regularly used in "normal" psytrance.The German artist Xenomorph, Mark Petrick, is considered a pioneer of dark psytrance, with his album "Cassandra's Nightmare" released in 1998 being a major influence on the subgenre; X-Dream's "Radio" is another 1998 album cited as an early influence.
