I put off buying this one for a while because of bad reviews and comments I had heard about it. But I finally bought a copy very early this year.
IMHO, probably not the best read ever, does go into a bit of detail on the recording of projects, I thought it skimmed over the Japan era a little fast. I also found myself having to re read parts I am sure it "jumped a bit" in places.
All and all though, worth getting for your collection, (I suggest trying
www.abebooks.com for a copy - you shouldn't need to pay much more than $10US for a copy). And as mentioned early, unless David ever writes an autobiography (and really how likely is that folks?), this is probably the best we will get on this genius!
Come to think of it, I wouldn't really want to see David's memoirs, it would spoil the mystery of the man and his arts.
