Well, that's it. It isn't an exhaustive list, there's plenty of other writers out there who write either similar to or like Charles Bukowski. Or maybe you like Hunter S. Thompson and his infamous "Fear And Loathing In Las Vegas." Or could be you got a thing for Chuck Palaniuk's pretty wide-ranging work. Good, popular examples: "Choke" and "Fight Club".
What about Ballard - author of "Crash" and a completely unrelated work: "Empire Of The Sun"?
The two titles couldn't be more different. I don't get much of his work, by the way, but I know there is something pretty powerful there. For me, his "Cocaine Nights" was the one that stood out.
