Harvey Phillip Spector (December 26, 1939 – January 16, 2021) was an American record producer, musician, and songwriter known for his innovative recording practices and entrepreneurship in the 1960s, followed decades later by his two trials and conviction for murder in the 2000s. Spector developed the Wall of Sound, a production style that he described as a Wagnerian approach to rock and roll. He is regarded as one of the most influential figures in pop music history and as the first auteur of the music industry for the unprecedented control he had over every phase of the recording process.
