Henry Millar springs to mind - Tropic of Cancer or the Rosy Crucifiction. I'd start with Tropic of Cancer.
My Idea of Fun by Will Self (if it's in print).
Bukowski - his poetry, or his novels - Post Office, Factotum or Women.
William Burroughs - Naked Lunch perhaps - his works can be read in several ways & Cain's book by Alexander Trocchi.
