As far as I am aware, this is the third incarnation of the book. The first edition I bought went as far as 1989, and the second edition 2002. I'm so glad it's been updated for the 50th anniversary. Each and every one of the Stones' 1,500+ studio and live recordings is listed, along with details (some copious, others brief) about when and where they were recorded, who was there, what they did and, where known, interesting asides and snippets of background information. There are lots of cross-references so you know where each track ended up (ie UK single, US single, album track, DVD, bootleg). Irritatingly for Martin Elliott, it must have gone to press about a nanosecond before they decided to record the two new tracks for Grrr. I have to admit I'm less interested in the live stuff than the studio stuff, but I love the fact that someone out there is even more obsessed than I am about the Stones' output and has chronicled it so lovingly. You can dip into it almost anywhere and immediately get drawn into a particular era of their history. I can't wait for the 2022 edition.
