On April 6th 1974 Deep Purple appeared on stage at the California Jam festival at the Ontario Speedway in California.

Taking top billing at the all-day event, and with great weather, Deep Purple and the other bands drew a crowd of around 165,000 people. It became the largest single-day paid attendance in U.S. rock concert history.

This astonishing concert is now the subject of a new documentary book, Deep Purple at the California Jam, published in December 2012 by Rufus Stone Limited Editions.

Collecting together hundreds of black and white and colour images from a number of photographers who had all area access to the concert (and rehearsals), the large 12" by 12" format presentation allows these images to shine. Many of the photographs have never been seen before and have been fully restored and colour corrected.

The book is available in three editions, from the astonishing Signature Edition, personally signed by Jon Lord, David Coverdale, Glenn Hughes and Ian Paice to a Vinyl edition and the book on it's own. The total run is just 1000 copies worldwide making this a true collectors presentation, whatever the format. A contribution from the sale of the Signature Edition will be made to Jon Lord's chosen. Jon Lord signed the book just three weeks before he passed away in July 2012.

A preview of he book can be found at www.rslimitededitions.com.

Jon Lord signed the book in June this year, just 3 weeks before he passed away and since then the pages have been on a trip around the world collecting the signatures of David Coverdale, Glenn Hughes and Ian Paice making this book a publishing event that cannot be repeated.
