Lifetime Hawkwind fan since '78, and great to see Dave still going with another incarnation. I never looked into the background much, but well aware of the members revolving door and it's miraculous they're not only still going, but have put out a record a year for the last decade.
As to this book, unless you're a Nik Turner fan, there's nothing else to recommend it. It's probably the worst written and edited ghost writing I've come across. The authorial voice keeps changing from Nik to 3rd person Nik, to ghost writer. The anecdotes jump around timelines and doesn't have a coherent narrative.
It's clear he believed himself keeper of the Hawkwind ideal, and spiritual leader, yet was one of its most disruptive members. This book just mythologizes Turner in his own words. He lays
claims to the band being named after him. Reading another Hawkwind bio that is more neutral, this is very much in dispute.
While Turner got Hawkwind a lot of free gigs, Dave Brock recruited members and kept HW going for 50+ years. Turner would have killed it in '72. He engineered Lemmy's sacking, then Dave was in his sights. Dave won that one and he and Lemmy always stayed friends. I never realised what a dickhead Turner was. Which is a shame, his sax was an integral part of the HW sound in the early 70s, and he did write a couple of their best loved tracks.
Turner also believed everyone had the right to do other projects as Hawkwind. Which is an unworkable idea. One he was sued for later on, when he toured as xhawkind. Brock would never have anything to do with him from then on. You'll find this book tainted by that history, and Nik's version will always make Nik look righteous. I bailed part way through, this was too much of a snowjob.
