The Wall of Sound is a music production technique for pop and rock music recordings developed by record producer Phil Spector at Gold Star Studios in Los Angeles, California, during the early 1960s. Working with such audio engineers as Larry Levine and the session musicians who became known as The Wrecking Crew, Spector created a dense, layered, reverberant sound that came across well on AM radio and jukeboxes popular in the era. He created this sound by having a number of electric and acoustic guitarists perform the same parts in unison, adding musical arrangements for large groups of musicians up to the size of orchestras, then recording the sound using an echo chamber.

To attain Spector's signature sound, his arrangements called for large ensembles (including some instruments not generally used for ensemble playing, such as electric and acoustic guitars), with multiple instruments doubling many of the parts to create a fuller, richer sound. Spector also included orchestral instruments - strings, woodwind, brass and percussion - not previously associated with youth-oriented pop music. Spector himself called his technique "a Wagnerian approach to rock & roll: little symphonies for the kids".

He is particularly recognized as the producer of the album Thriller, by pop icon Michael Jackson, which has sold more than 110 million copies worldwide, and as the producer and conductor of the charity song “We Are the World”.

In 1968, Jones and his songwriting partner Bob Russell became the first African Americans to be nominated for an Academy Award for Best Original Song "The Eyes of Love" from the Universal Pictures film Banning. That same year, he became the first African American to be nominated twice within the same year when he was nominated for Best Original Score for his work on the music of the 1967 film In Cold Blood. In 1971, Jones would receive the honor of becoming the first African American to be named musical director/conductor of the Academy Awards ceremony. He was the first African American to win the Academy's Jean Hersholt Humanitarian Award, in 1995. He is tied with sound designer Willie D. Burton as the most Oscar-nominated African American, each of them having seven nominations. At the 2008 BET Awards, Quincy Jones was presented with the Humanitarian Award. He was played by Larenz Tate in the 2004 biopic about Ray Charles, Ray.

Phillip Harvey "Phil" Spector (born Harvey Phillip Spector on December 26, 1939) is an American record producer and songwriter.

The originator of the "Wall of Sound" production technique, Spector was a pioneer of the 1960s girl-group sound and produced over 25 Top 40 hits in 1960–1965. Some of his famous girl groups are The Ronettes and The Crystals. After this initial success, Spector later worked with artists including Ike and Tina Turner, John Lennon, George Harrison, and the Ramones with similar acclaim. He produced The Beatles' Academy Award winning album Let It Be, and the Grammy Award–winning Concert for Bangladesh by former Beatle George Harrison. In 1989, Spector was inducted into the Rock and Roll Hall of Fame as a non-performer. The 1965 song "You've Lost That Lovin' Feelin'", produced and co-written by Spector for The Righteous Brothers, is listed by BMI as the song with the most U.S. airplay in the 20th century.

In 2009 Spector was convicted of second-degree murder in the 2003 shooting death of actress Lana Clarkson in his Alhambra, California home. He is serving a prison sentence of 19 years to life.

Tina Turner (born Anna Mae Bullock; November 26, 1939) is an American singer and actress whose career has spanned more than 50 years. She has won numerous awards. Turner started out her music career with husband Ike Turner as a member of the Ike & Tina Turner Revue. Success followed with a string of hits including "River Deep, Mountain High" and the 1971 hit "Proud Mary". With the publication of her autobiography I, Tina (1986), Turner revealed severe instances of spousal abuse against her by Ike Turner prior to their 1976 split and subsequent 1978 divorce. After virtually disappearing from the music scene for several years following her divorce from Ike Turner, she rebuilt her career, launching a string of hits beginning in 1983 with the single "Let's Stay Together" and the 1984 release of her fifth solo album Private Dancer.

Her musical career led to film roles, beginning with a prominent role as The Acid Queen in the 1975 film Tommy, and an appearance in Sgt. Pepper's Lonely Hearts Club Band. She starred opposite Mel Gibson as Aunty Entity in Mad Max Beyond Thunderdome for which she received the NAACP Image Award for Outstanding Actress in a Motion Picture, and her version of the film's theme, "We Don't Need Another Hero", was a hit single. She appeared in the 1993 film Last Action Hero.
