If you like your psytrance dark, manic and a little old school you should try the latest offering from Temple Twister titled 'Lethal Dose'.
Paranoize, Kerosene Club, Kindzadza, Wizard Lizard and Dark Nebula, amongst others, offer a highly charged and edgy complilation full of fast and furious tracks.
Not for everyone's taste but will please the fans of this genre.
