Charlie Gillett - Making Tracks: The History Of Atlantic Records

This book was first published in 1975 from which my copy dates (yes I am that old). The fact that it is still a recommendation on the Shades site today today speaks volumes for its importance to any R&B lover out there with the slightest interest in one of the great R&B labels.

One of the best histories of big business and the recording industry you are ever likely to find. An excellent behind the scenes study of Atlantic Records from its inception as a part time hobby of Herb Abramson through to its critical role in popular music as one of the leading labels of the 50s and 60s. Good insight into what made a 50s label tick, the 'hit and miss' nature of its releases, especially early on, all add to the interest. The labels 'movers and shakers' didn't have that much business know how early on and Atlantic survived those early days as much by luck as by good judgement

Lot’s of excellent information on Atlantic luminaries such as Ray Charles, Aretha, Bobby Darin, Crosby, Stills Nash and Young and Led Zeppelin.

Other than Jerry Wexler's autobiography (very partial but highly enjoyable), probably the best overview of Atlantic Records you're ever likely to read.
This is one that you'll definitely need the library for. If you do a lot of digging you might be able to source a copy, but it'll probably be a long search!.
