Interest in Pink Floyd remains as intense as ever even 40 years after the release of Dark Side of the Moon with lavish box-sets collecting demos & out-takes & Roger Waters' world tours of The Wall playing to packed stadiums. Now Mark Blake's superbly comprehensive & engrossing history of the group rightly acclaimed as the definitive book on the band has been fully revised & extended with new interviews to bring the story up to date with the recent appearances of David Gilmour & Nick Mason with Roger Waters at a London date on his The Wall tour.
