Several terms were introduced, such as "blue-eyed soul", which is R&B or soul music performed by white artists. The meaning of blue-eyed soul has evolved over decades. Originally the term was associated with mid-1960s white artists who performed soul and R&B that was similar to the music released by Motown Records and Stax Records. The Righteous Brothers, The Rascals, Spencer Davis Group, Steve Winwood, Van Morrison & Them and The Grass Roots were famous blue-eyed soul musicians in 1960s. The term continued to be used in the 1970s and 1980s, particularly by the British media to refer to a new generation of singers who adopted elements of the Stax and Motown sounds. To a lesser extent, the term has been applied to singers in other music genres that are influenced by soul music. Artists like Hall and Oates, David Bowie, Teena Marie, Hamilton, Joe Frank & Raynolds, Frankie Valli, Christina Aguilera, Amy Winehouse and Adele are known as blue-eyed soul singers.
