Englands dreaming, altered states, rip it up and start again as mentioned, dirt for scary comedy. also would add in:
Fargo Rock city - Chuck Klosterman (As twisted mentions earlier) is one of the funniest rock books i have ever read if you have ever liked heavy metal from the 80s read it and weep with laughter as he reminices and is a fantastic list maker his reviews of some of the hair metal videos and what they say about he bands sexual proclivites had me in stitches.
The history of creation records: My magpies eyes have stolen the prize by David Kavanagh is great and gives you a micro detailed history from postcard records to oasis overload etc
Have gun will travel the spectacular rise and fall of death row records - ronin ro is good if not really my cup of tea musically.
and I should mention Ginger Geezer, recent and very good biog of viv stanshall (as one of my mates co-wrote it)
Oh and revolution in the head - Ian macdonald....if you are a beatles nut and you want to know what snare sound was used on paperback writer...it;ll be in here if its anywhere.
Black vinyl white powder - simnon napier bell is quite a good romp.
