Yeah, sort of. It's got some antedotal stuff about Bunny Lee and Lloyd Daley and Lee Perry. The focus is on the development of the label in the UK (and Island records too) and that's pretty interesting in itself.
The book on reggae that I read recently that you'd probably really really enjoy is 'Solid Foundation: An Oral History of Reggae' by David Katz (who also did a great Lee Perry book btw). He had access to interview virtually everyone who was anyone if they were still alive and it's very well written so it tells a story and has a good flow to it (it's not just a bunch of interviews thrown together). The Katz book mostly concerns itself with the pre-Reggae era through what would more or less be the end of the 70s/early 80's. Of course that means lots of great stuff on the pioneers of ska, rocksteady and early reggae
