Hmmm...
It's easy to make stuff that sounds good when yr f*cked, isn't it... But then its good to get an idea of how it sounds when yr wrecked too...
Play about with it in what ever state you fancy, but do the hard work straight.
Weed - I tend to get bored and listen the the same four bars over, just not too productive!
Acid - did a really good jam once, all wierd and swirly with Absynth and some live bits and bobs... Still sounds great, but it's 65 bloody minutes long!!!!
K - Are you mad!!! Tried it once when my mate shoved his laptop infront of me. Somehow managed to write a drum loop, but at the time the Laptop was mutating into a swamp complete with crocodiles! And it make it all sound tinny.
Beer - Tend to get bored and want to look at tits on the net instead...
