I'd like to recommend "The History of House" compiled and edited by Chris Kempster.
Although it's called "...History of House" they also include Detroit's role in the history. The book is divided into 3 parts: Part 1: The Artists - USA, Part 2: The Artists - UK & Europe, and lastly, Part 3: The Technology (for all you gear hoars) =). Got this one at Recordtime in 1996. Alot of interesting details in it. Peace, G l y p h
