It reminds me of that scene in 2001: A Space Odyssey, where the Black Monolith transforms mere apes into Humans, and Humans into the Star Child. Bill Hicks reached a new evolutionary paradigm with this material as he had ditched much of his more puerile and ad nauseam material (e.g. 'Your Kids aren't Special'), in favour of stuff that is more insightful and wittier.
An example of this is 'Hooligans', which is THE funniest bit of Stand-up ever, and there is much material that is hilarious and resonant even today (e.g. 'The Elephant is dead (Bush)' - what with the latest Bush incarnation dead & gone!)
Of course, the material is still offensive, but one gets the impression that Hicks got past his childish offense-for-offense's-sake phase, and hence achieved his prophetic heights. It also benefits from having been edited by Kevin Booth & so being less indulgent of his dark tendencies.
As is the cliche, it is an enormous pity he died so young, as what he could have achieved after this album is anyone's guess. Maybe what we see in the artists who produced the real Dark Side of the Moon, is what Bill Hicks would have become - not always as brilliant as their (his) creative peak, but truly inspiring and enriching when he was on top form...
