Inner City Blues (Makes Me Wanna Holler) - Marvin Gaye (1971)
Marvin Gaye was the master of smooth R&B, but there is nothing smooth about this song's message from his seminal album. The world has gone to hell, especially in the inner city. Not only did this song influence modern soul up to the present, it tought Motown that it was perfectly acceptable to be reliant on a preformer's writing and production skills!
Listen to Etta turn up the funky knob!
