Hmm, I know I recently downloaded some trance with Fear and Loathing samples in it... Might have been either 1200 Micrograms or Hallucinogen. I won't be able to check my home computer until tomorrow, though, sorry I can't be more specific.
edit: Try the song "Mescaline" by 1200 Micrograms. I think that might be it, and a quick google search seems to confirm this.
