I can't recommend anyone higher than Mick Farren: The DNA Cowboys Trilogy, The Texts of Festival, The Song of Phaid the Gambler and many others. He's an obscure English ex-hippy musician who probably did a few too many drugs in the 60s & 70s and if you know anything about him you'll realise that he writes himself into all of his own books as the hero ((in the DNA Cowboys' books he manages to write himself as both of the heroes). He's not a very consistent author but he's well worth a read. I've read most of his books several times over the years and I never cease to get enjoyment from them. And his book on the history of the Black Leather Jacket is a good read too.
