I can't understand why there hasn't been more 'Psy-DnB'... I'm not a massive fan of Psy-trance, mainly because of the typical rolling bassline in EVERY tune, but the trippy sounds and crazy progressions you get in Psy genres are sick.
Telemetrik's probably worth mention in here as well - 'My Light Year's one of my top DnB albums and I'd say it's pretty psychedelic in places and quite progressive in the way he structures his tunes. Definitely worth checking out!
