The Sound of Philadelphia, Cummings
It was written at arguably the absolute peak of the fabulous 70's output of soul and disco music from Philadelphia. Tony Cummings' emphasis is 100% on the music,rather than the tales of disgruntled former colleagues of Kenny Gamble/Leon Huff/Thom Bell. He delves deep into doo-wop and r&b history (of which he has an encyclopedic knowledge)to find the story of soul from "The City Of Brotherly Love". If you like collecting soul from Philly, this book give you lots of leads towards obscure singles and albums that are largely forgotten today. Condition is very good.
