Track 2 sample - the (contemporary) classical section is taken from Chi Mai by Ennio Morricone. (Chi Mai was written for the 1981 BBC television series 'The Life & Times of David Lloyd George' - the title of which presumably inspired the name of Acen's track here).
Track 3 samples - "Just close your eyes / forget your name / forget the world / forget the people / go insane" from The Celebration of the Lizard by The Doors and "overdose" from Mr Kirk's Nightmare by 4 Hero.
