No correlation sorry. I know people who barely touch alcohol and make more mind altering music than anything by today's 'cid drinking dark psy producers. Sorry, the music comes from the mind and not anything else. Yes, most of the psy producers had psychedelic experiences, yes, without LSD there would be no Beatles (unless you call their pre-LSD music worthy) no Jimmy Hendrix, no Pink Floyd and certainly no Psy Trance or Goa. But, there are artists that don't.
