If you're a serious fan of early Pink Floyd (pre 1973), chances are that you collect unauthorized concert recordings of the band. This is because they performed a lot of music in very unique versions that still can't be obtained from official sources. This is especially true of Floyd's 1968-72 period. The big problem is in knowing and verifying the basic facts of RoIO albums, such as dates, venues and songs. The world of RoIO albums is marked by a lack of information and much completely wrong information, sometimes deliberately done unfortunately. Many of the same RoIO source recordings are continuously re-named, re-packaged and reissued with differing information, which presents a huge challenge to the collector to avoid getting duplicates or otherwise unwanted albums.
"Pink Floyd: In the Flesh" is an indispensable guide to all the fine details of each Floyd show, from the entire spectrum of their performing career. Besides being fascinating reading, I've found the book invaluable in helping me make sense of the vast number of RoIO albums out there. It's directly helped me make some worthwhile purchases of RoIO albums. For a Floyd concert collector, I cannot recommend this book highly enough.
