I read this book in the mid nineteen seventies. It definitely stayed with me. I still retain the sense of longing and searching it stoked in me then, mere embers now. I suppose I'm an old hippy of sorts. Of course it's of its time like most things, yet cool cats will always be cool. Regardless of when they were born or irrespective of what we call them. These "Angel Headed Hipsters", eschewed the notion of dressing or sounding like their parents generation, but instead, replete in their own understated sartorial elegance, they chose to search for "The Birth of the Cool" echoing from the hallowed halls of the likes of "Birdland" or the myriad smokey underground clubs frequented by a burgeoning counter culture of young beatniks, just begining to discover a hitch hiking way of life, embraced almost universally by their erstwhile hippy successors a decade or so later. There's a famous photo of Bob Dylan standing at the grave of Jack Kerouac, paying homage perhaps. It speaks volumes. Well worth a read.
