I just reread this (having first bought it whenever it came out, back in 1997, I think), and found it to be a very interesting history/analysis of raving in the UK. My reason for not giving it four stars is that the author makes no attempt to explain why ecstasy became so popular, so quickly in the UK when it had previously been available elsewhere (notably in the states). Did it have something to do with Britain at the time (in the latter years of a Thatcher government, with those awful licensing laws), or supply (people could just buy it here more easily)?
There may be a bit much made of the effect of individuals too (x did this and then y did that, as if they created changes themselves), but even so, most of those individuals were interesting.
What I liked most about the book is that having focused on the initial boom, it then went on to look at what happened afterwards. I particularly liked the bit about Spiral Tribe (partly because at the time, for a moment, I thought that there might be some kind of youth revolution - I was young and, of course, wrong, but just for a moment there it was kind of exciting).
It would be interesting to read what the author would have to say about what has happened since 1997. Dance music no longer occupies the mainstream. Dull rock bands rule again (be they Coldplay or the Arctic Monkeys, there's nothing really that new going on). Politically, did the whole ecstasy generation thing give rise to the focus group approach with which Labour has been so successful? Was ecstasy the ultimate Thatcherite coup de grace, making even the disenfranchised selfish?
