In a recent issue in Guitar Player, there was a review for a book called "Strange Brew-Eric Clapton & the British Blues Boom 1965-1970" written by Christopher Hjort. The review was really good so I ordered a copy from Amazon. Just got it and was totally blown away. Lot's of history and great pics of Clapton, Peter Green, Mick Taylor etc... If you are into that period of music, I highly recommend it!
