Ok I'm not a psychiatrist..... but I guess it's a well-known fact that there's a connection between the weather and the creative output of people who are moody and sensitive.
If you are affected by the weather, what you're gonna do when it's grey and rainy? You're gonna sit inside and think, and if you have any creative urge, whether it'd be music, painting, writing, etc., you're gonna want to get in out.
Whilst Morrissey was living in Manchester or London, he had plenty of time to sit inside and think about his past, upbringing, the meanness of the world etc..... Thus he always had something to write about. Along with that might have come a desire to get away and tour as often as possible. Could be. Touring brought new experiences, new soil for creativity, etc.......
So now he lives in L.A. and the sun's beaming down on him all day. I'm not still claiming all he does is drive down the boulevards in his Porsche, but the new sunnier life certainly had an effect on his creative output....Since 98 he's done one tour and apparantely one album which only exists in theory.
Now judging on myself, I can certainly relate to that..... I usually write my best stuff in autumn and winter, when I'm traditionally most depressed aswell. That doesn't mean that I only write depressing stuff, but that I take out more time to "connect" to my inside. These days when it's hot, all worries, thoughts, catastrophes make me go "yeah, whatever". Life's just smoother and lived more for the moment......... Yesterday while it was boiling hot all day I hardly ever got off the sofa and my most upfront concern was in which order to empty the fridge.
Here I go again......though I've changed my conclusion slightly from saying that L.A.'s not good for Morrissey to: L.A. is probably good for Morrissey and thus unfortunately not good for us. I hope that at least he manages to put out a worthy swan song before he retires in the sunshine for good.
