I fuckin' love gonzo. Nothing gets me pumped like reading some outrageously transgressive shit. Sex? Check. Violence? Check. Drugs? Check. Depravity? Check. Obviously it's not just those things. But it sounds a lot like it's those things. Or, at least, it rhymes likes those things.
I remember reading Henry Miller's Quiet Days in Clichy. Small book, insignificant in many ways, yet not at all. You should read it. That man could write. I first read The Colossus of Maroussi, that's where I found out about him as a writer, but the Clichy stories, that was Gonzo.
He talks about fucking hookers, about eating leftovers out of the garbage, about helping his friend get out of trouble with an underage girl. He also talks about traveling to Luxembourg and generally living the starving artist lifestyle. It's a proper intro to Gonzo, yet it is still highly literary.
Bukowski? He just didn't give a fuck. HST? He invented the term, but I'm still always going to go back to Miller on originality. There's a reason his books were banned back when they were initially published. Plus, he could write. It wasn't sensationalism.
But the real reason I love the style is that it's raw and it's honest. It's a perfect first draft, unedited and ugly, but...perfect.
