LL Cool J

Context: James Todd Smith was born on January 14, 1968, in Bay Shore, New York, the son of Ondrea Griffeth (born January 19, 1946) and James Louis Smith, Jr. In an episode of Finding Your Roots, LL learned his mother was adopted by Eugene Griffith and Ellen Hightower. The series' genetic genealogist CeCe Moore identified LL's biological grandparents as Ethel Mae Jolly and Nathaniel Christy Lewis through analysis of his DNA. LL's biological great-uncle was hall of fame boxer, John Henry Lewis.  He began rapping at the age of 9, influenced by the hip-hop group The Treacherous Three. In March 1984, sixteen-year-old Smith was creating demo tapes in his grandparents' home. His grandfather, a jazz saxophonist, bought him $2,000 worth of equipment, including two turntables, an audio mixer and an amplifier. Smith stated that "By the time I got that equipment, I was already a rapper. In this neighborhood, the kids grow up in rap. It's like speaking Spanish if you grow up in an all-Spanish house. I got into it when I was about 9, and since then all I wanted was to make a record and hear it on the radio." This was at the same time that NYU student Rick Rubin and promoter-manager Russell Simmons founded the then-independent Def Jam label. By using the mixer he had received from his grandfather, Smith produced and mixed his own demos and sent them to various record companies throughout New York City, including Def Jam.  In a VH1 documentary (Planet Rock: the Story of Hip Hop and the Crack Generation), LL Cool J, at 14 years of age, revealed that he initially wanted to call himself J-Ski but did not want to associate his stage name with the cocaine culture (the rappers who use "Ski" or "Blow" as part of their stage name e.g., Kurtis Blow, Joeski Love were associated with the rise of the cocaine culture as depicted in the 1983 remake of Scarface).  Under his new stage name, LL Cool J (an abbreviation for Ladies Love Cool James), Smith was signed by Def Jam, which led to the release of his first official record, the 12-inch single "I Need a Beat" (1984). The single was a hard-hitting, streetwise b-boy song with spare beats and ballistic rhymes. Smith later discussed his search for a label, stating "I sent my demo to many different companies, but it was Def Jam where I found my home." That same year, Smith made his professional debut concert performance at Manhattan Center High School. In a later interview, LL Cool J recalled the experience, stating "They pushed the lunch room tables together and me and my DJ, Cut Creator, started playing. ... As soon as it was over there were girls screaming and asking for autographs. Right then and there I said 'This is what I want to do'." LL's debut single sold over 100,000 copies and helped establish both Def Jam as a label and Smith as a rapper. The commercial success of "I Need a Beat", along with the Beastie Boys' single "Rock Hard" (1984), helped lead Def Jam to a distribution deal with Columbia Records the following year.  LL Cool J married Simone Smith in 1995. They have four children.  Radio was released to critical acclaim, both for production innovation and LL's powerful rap. Released November 18, 1985, on Def Jam Recordings in the United States, Radio earned a significant amount of commercial success and sales for a hip hop record at the time. Shortly after its release, the album sold over 500,000 copies in its first five months, eventually selling over 1 million copies by 1988, according to the Recording Industry Association of America. Radio peaked at number 6 on the Top R&B/Hip-Hop Albums chart and at number 46 on the Billboard 200 albums chart. It entered the Top R&B/Hip-Hop Albums chart on December 28, 1985, and remained there for forty-seven weeks, while also entering the Pop Albums chart on January 11, 1986. Radio remained on the chart for thirty-eight weeks. By 1989, the album had earned platinum status from the Recording Industry Association of America (RIAA), after earning a gold certification in the United States on April 14, 1986, with sales exceeding one million copies. "I Can't Live Without My Radio" and "Rock the Bells" were singles that helped the album go platinum. It eventually reached 1,500,000 in US sales.  With the breakthrough success of his hit single "I Need a Beat" and the Radio LP, LL Cool J became one of the first hip-hop acts to achieve mainstream success along with Kurtis Blow and Run-D.M.C.. Gigs at larger venues were offered to LL as he would join the 1986-'87 Raising Hell tour, opening for Run-D.M.C. and the Beastie Boys. Another milestone of LL's popularity was his appearance on American Bandstand as the first hip hop act on the show, as well as an appearance on Diana Ross' 1987 television special, Red Hot Rhythm & Blues.  The album's success also helped in contributing to Rick Rubin's credibility and repertoire as a record producer. Radio, along with Raising Hell (1986) and Licensed to Ill (1986), would form a trilogy of New York City-based, Rubin-helmed albums that helped to diversify hip-hop. Rubin's production credit on the back cover reads "REDUCED BY RICK RUBIN", referring to his minimalist production style, which gave the album its stripped-down and gritty sound. This style would serve as one of Rubin's production trademarks and would have a great impact on future hip-hop productions. Rubin's early hip hop production work, before his exit from Def Jam to Los Angeles, helped solidify his legacy as a hip hop pioneer and establish his reputation in the music industry.  LL Cool J's second album was 1987's Bigger and Deffer, which was produced by DJ Pooh. This stands as his biggest-selling career album, having sold in excess of three million copies in the United States alone. It spent 11 weeks at #1 on Billboard's R&B albums chart. It also reached #3 on the Billboard's Pop albums chart. The album featured the singles "I'm Bad", the revolutionary "I Need Love" - LL's first #1 R&B and Top 40 hit, "Bristol Hotel", and "Go Cut Creator Go". LL Cool J's third album was 1989's Walking with a Panther. Released in 1989, the album was a commercial success, with several charting singles ("Going Back to Cali," "I'm That Type of Guy," "Jingling Baby," "Big Ole Butt," and "One Shot at Love"). The album however was often criticized by the hip-hop community as being too commercial and materialistic, and for focusing too much on love ballads. According to Billboard, the album peaked at #6 on the Billboard 200 and was LL Cool J's second #1 R&B Album where it spent four weeks.  While the previous album Bigger and Deffer, which was a big success, was produced by The L.A. Posse (at the time consisting of Dwayne Simon, Darryl Pierce and, according to himself the most important for crafting the sound of the LP, Bobby "Bobcat" Ervin), Dwayne Simon was the only one left willing to work on producing Walking with a Panther. Bobcat said he wanted more money for the album after realizing how much of a success the previous album really had become but Def Jam refused to change the contract which made him leave Cool J. According to Bobcat this is the reason that Walking with a Panther was met with very mixed reception at the time of its release.  In 1990, LL released "Mama Said Knock You Out", his fourth studio album. The Marley Marl produced album received critical acclaim and eventually went double Platinum selling over two million copies according to the RIAA. LL won a Grammy Award for Best Rap Solo Performance in 1992 for the title track. CANNOTANSWER
