Harvey Phillip "Phil" Spector was an American record producer and songwriter best known for his innovative recording practices and entrepreneurship in the 1960s and his two trials and conviction for murder in the 2000s. Spector developed the Wall of Sound, a production style that is characterized for its diffusion of tone colors and dense orchestral sound, which he described as a "Wagnerian" approach to rock and roll. He is widely regarded as one of the most influential figures in pop music history and one of the most successful producers of the 1960s.

An auteur is an artist with a distinctive approach, usually a film director whose filmmaking control is so unbounded and personal that the director is likened to the "author" of the film, thus manifesting the director's unique style or thematic focus. As an unnamed value, auteurism originated in French film criticism of the late 1940s, and derives from the critical approach of André Bazin and Alexandre Astruc, whereas American critic Andrew Sarris in 1962 called it auteur theory. Yet the concept first appeared in French in 1955 when director François Truffaut termed it policy of the authors, and interpreted the films of some directors, like Alfred Hitchcock, as a body revealing recurring themes and preoccupations.
