Steve Kilbey of the Church tells about music during the drug years 

Woke up this morning and played my vinyl of Priest = Aura, coffee, 5 beers and an edible. It's a masterpiece

the fogged spirit projects music that will resonate with those that are on the same medicines per se. sometimes it is easier just to write when you are messed up because you get used to writing when you are messed up and it can be a problem if you want to write when you are clean and no one is writing with you etc it can be demeaning and feel like theres no use to being creative when your sober even though thats when your spirit is most there as opposed to being used to writing and needing it when you are on something
