^^^ Just read that myself not too long ago.
It's a really fun read. It's really fun traveling along with the band on their tour; i imagine even non fans would find it to be an enjoyable read. The interview sections are indeed illuminating, although i will admit to skimming through the more dedicated 'technical' section at the end; just found it too dense although i have every intention of revisiting it. I found the technical/theory parts peppered throughout the road trip and conversations with Graham Lock more bite sized and therefore easier to digest.
