I'd forgotten about Chet Forest and his role in making of "What's Going On". His job was to help Marvin take the "Motown Sound" out of a Motown record. Marvin was the company's rebel and had little patience for it's tendency to rely on a signature sound over an artist's talent. Most of the battles he had with Berry Gordy was his agitation of B.G's value in his looks as opposed to his extraordinary talents as a vocalist. So he wanted to show the company that it didn't really need what it relied on to have a hit. He wanted anything, but what was considered "Motown" even down to the mixing and Chet played a big part in delivering that.

It's really good to marvel at how good Marvin and Stevie could play on early recordings. Marvin's explosive playing on Stevie's "I Call It Pretty Music, Part One" is pretty impressive. Stevie's consistent beat on The Tops "Loving You Is Sweeter Than Ever" is a prime example of his trap skills and what he learned from Benny B.
