R. City (short for Rock City; and formerly Planet VI) is a U.S. Virgin Islands musical duo formed in 2003, from Saint Thomas, U.S. Virgin Islands. The duo consists of brothers Theron "Uptown AP" Thomas and Timothy "A.I." Thomas. Primarily known as a songwriting and record production team, the duo has also released various bodies of work as recording artists, including their debut album, What Dreams Are Made Of, released in November 2015. They are best known for the single "Locked Away" featuring Adam Levine.
In 2007, the duo signed with Geffen Records and American singer Akon's KonLive Distribution. During their time there they released a series of mixtapes with the primary title, PTFAO (Put the F*ckin' Album Out), a reference to the fact that their then-debut album Wake the Neighbors had not been given a release date. In 2011, the duo were released from their contract with KonLive and subsequently founded Rebelution Records. In 2014, they signed a record deal with RCA Records and Dr. Luke's Kemosabe Records.
The Thomas brothers have written and produced for several prominent artists, including Jamaican singer Sean Kingston ("Take You There"), American singer Miley Cyrus ("We Can't Stop"), Trinidadian rapper Nicki Minaj ("Only") and Barbadian popstar Rihanna ("Pour It Up"). The duo has also contributed to numerous Grammy-nominated albums, including Rihanna's Unapologetic (which won Best Urban Contemporary Album), Jennifer Hudson's self-titled album (which won Best R&B Album), and Ariana Grande's My Everything (which was nominated for Best Pop Vocal Album).
