J-Swift is an Afro-Cuban American music producer responsible for songs with groups on the Delicious Vinyl Label. He has produced the hip hop groups The Pharcyde and The Wascals.

Hip-hop producer J-Swift was born Juan Manuel Martinez in 1971 in Madrid, Spain. His Afro-Cuban father was a salsa bandleader and multi-instrumentalist. In 1974 the family headed to Los Angeles, California, settling in Inglewood. At age six, J-Swift enrolled in a piano conservatory, quickly proving to be a prodigy. The all-rap radio station KDAY introduced him to hip-hop in the early ‘80s, and the first record he ever got was by Grandmaster Flash and the Furious Five.

Around 1988 J-Swift met R&B musician Reggie Andrews, producer of Dazz Band’s 1982 funk hit “Let It Whip.” After J-Swift composed three New Jack Swing-style songs to get his attention, Andrews suggested that he concentrate on writing and producing, and set him up with a recording studio (complete with a then-state-of-the-art Akai MPC60) at South Central Unit (SCU), an after-school program for disadvantaged young talent. This gave J the opportunity to submit songs to A&M Record’s Rondor Music publishing, while additional work came via BMI’s Cheryl Dickerson. Though much of this early music went unreleased (like an album by Bell Biv DeVoe spin-off STR8-Ahead), J-Swift’s official songwriting/producing debut came in 1991 with Keisha Jackson’s “Feel You Out.”

After scoring her first number one in the United Kingdom, France, Ireland and New Zealand with the song "Price Tag", she released her debut album Who You Are (2011) which charted at number two in the UK. Other releases from the album include "Nobody's Perfect", "Who's Laughing Now" and "Who You Are" which charted within the top 20 in the UK but the release of fifth single "Domino" spawned international chart success, peaking at number 6 on the Billboard Hot 100 in the US, and becoming her second UK number one. Aside from her musical career, Jessie J is currently a coach and mentor on television show The Voice UK.

The release of Swift's self-titled debut album in 2006 established her as a country music star. "Our Song", her third single, made her the youngest sole writer and singer of a number one song on the country chart. She received a Best New Artist nomination at the 50th Grammy Awards.

Swift's second album, Fearless, was released in late 2008. Buoyed by the chart success of the singles "Love Story" and "You Belong with Me", Fearless attracted a crossover audience and became the top-selling album of 2009. The record won four Grammy Awards, with Swift becoming the youngest ever Album of the Year winner. Fearless also received Album of the Year plaudits at the American Music Awards, Academy of Country Music Awards and Country Music Association Awards, making it the most awarded album in country music history. In 2010, Swift released her third album, Speak Now, which sold over one million copies in its first week. She then embarked on the 111-date Speak Now World Tour, which was attended by over 1.6 million fans and has become one of the highest-grossing concert tours of all time.
