The essence is certainly gothic, there are rambling, lonely, horny, alienated males in groups, even if they are females. And no matter how crap they are, and they are extraordinary loyal to the tribe. Where else would you get Rick Wakeman and Keith Emerson and Jon Lord and every other idiot chewing the cud over the pleasures of never doing 'Smoke on the Water on Ice'.
Meanwhile, I'm reading Keef's biography 'Life' and thrilled that it's a bestseller (illustrating that........you answer that question). It's also amazingly good.
