Motown and the music of the 60’s encompassed a golden age of music. Surround yourself with the key Motown artists: Marvin Gaye, Smokey Robinson, The Four Tops, and The Jackson 5.
Also don’t forget the music of Stax out of Memphis and Muscle Shoals Alabama. This would include Otis Redding, Albert King, Sam And Dave, Booker T. and the MG’s, and Isaac Hayes to name a few. These artists ran parallel in time to Motown’s golden age and produced music of equal quality.
Oh yeah, and Michael Jackson is always a safe bet too.
