What is "blue-eyed soul"

n. rhythm and blues or soul music performed by white artists.

Blue-eyed soul (also known as white soul) describes rhythm and blues and soul music performed by white artists. The term was coined in the mid-1960s, to describe white artists who performed soul and R&B that was similar to the music of the Motown and Stax record labels. Though many rhythm and blues radio stations would only play music by black musicians, some began to play music by white acts considered to have "soul feeling", which came to be called "blue-eyed soul".
