Phillip Harvey "Phil" Spector is an American record producer, songwriter, and the originator of the Wall of Sound production method. At the height of his career, Spector was a pioneer of the 1960s girl-group sound, and produced more than twenty-five Top 40 hits from 1960 to 1965, writing or co-writing many of them. In later years, he gained infamy as the subject of two trials for murder and a second-degree conviction.
Spector is often called the first auteur among musical artists for acting not only as a producer, but also the creative director, writing or choosing the material, supervising the arrangements, conducting the vocalists and session musicians, and masterminding all phases of the recording process. He helped pave the way for art rock, and helped inspire the emergence of aesthetically-oriented genres such as dream pop, shoegaze, and noise. Among his famous girl groups were the Ronettes and the Crystals; later working with artists including Ike and Tina Turner, John Lennon and the Ramones with similar acclaim. He produced the Beatles' album Let It Be, and the Grammy Award-winning Concert for Bangladesh by former Beatle George Harrison.
