They may have been called Dennis Coffey and the Detroit Guitar Band but damn it's all about the drums in this one. From the Young MC Bust a Move sample at 1:10 to the bongos kicking in at 1:20. OMG eargasms.
Kenny Gamble and Leon Huff were a writer/producer duo based in Philadelphia and started a record label in 1971 entitled Philadelphia International. They were instrumental in developing the Philly Soul sound which was the precursor to disco. Before that they did a few things including collaborating on the song I'm Gonna Make You Love Me which was a hit for Diana Ross and The Supremes. Their first major production credit was in 1967 for the Soul Survivors - Expressway To Your Heart. It peaked at #5 on the charts
Also in 1972 Gamble and Huff along with colleague Bunny Sigler hit paydirt writing and producing the O'Jays debut album Backstabbers which reached the Billboard top 10 and certified gold status in its first year of release. It produced a #1 hit in Love Train while Backstabbers reached #3. But seriously the whole album is mint. It's a musical masterpiece.
Then it was Teddy time. Gamble and Huff wrote and produced Teddy Pendergrass' first three solo albums. With a little help from another soul producer/writer/composer duo McFadden & Whitehead.
The Jones Girls were signed to Philadelphia International after performing as backup singers for Lou Rawls, Teddy Pendergrass and Aretha Franklin. Originally from Detroit Gamble and Huff decided to sign them to their label in 1979 and produced a few moderate hits for them. This one hit #5. Great bass sound.
