Rock City (duo)

Rock City, also known as R. City and Planet VI, is an American musical duo from Saint Thomas, U.S. Virgin Islands, formed in 2003. The duo, composed of brothers Theron and Timothy Thomas, who use the stage names, A.I. and Uptown AP respectively, are also a songwriting and record production team. The Thomas brothers also write and produce for other artists, including Jamaican artiste, 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).

Rock City also releases original music, having released several mixtapes since 2008. The group had previously been signed to Geffen Records and KonLive, where they released a series of mixtapes with the primary title, PTFAO (Put the F*ckin' Album Out)—a reference to the fact that their debut album Wake the Neighbors, had not been given a release date. In 2011, the duo was released from their contract with KonLive, and founded Rebelution Records, on which they intended to release their debut album. A new album, What Dreams Are Made Of, is due to be released in 2015, after being signed to Kemosabe Records and RCA Records by Dr. Luke.

City

A city is a large and permanent human settlement. Although there is no agreement on how a city is distinguished from a town in general English language meanings, many cities have a particular administrative, legal, or historical status based on local law.

Cities generally have complex systems for sanitation, utilities, land usage, housing, and transportation. The concentration of development greatly facilitates interaction between people and businesses, benefiting both parties in the process, but it also presents challenges to managing urban growth.

A big city or metropolis usually has associated suburbs and exurbs. Such cities are usually associated with metropolitan areas and urban areas, creating numerous business commuters traveling to urban centers for employment. Once a city expands far enough to reach another city, this region can be deemed a conurbation or megalopolis. In terms of population, the largest city proper is Shanghai, while the fastest-growing is Dubai.

Origins

There is not enough evidence to assert what conditions gave rise to the first cities. Some theorists have speculated on what they consider suitable pre-conditions and basic mechanisms that might have been important driving forces.

Music video

A music video or song video is a short film integrating a song and imagery, produced for promotional or artistic purposes. Modern music videos are primarily made and used as a marketing device intended to promote the sale of music recordings. There are also cases where songs are used in tie in marketing campaigns that allow them to become more than just a song. Tie ins and merchandising could be used in toys are marketing campaigns for food and other products. Although the origins of music videos date back to musical short films that first appeared in the 1920s, they came into prominence in the 1980s when MTV based their format around the medium. Prior to the 1980s, these works were described by various terms including "illustrated song", "filmed insert", "promotional (promo) film", "promotional clip", "promotional video", "song video", "song clip" or "film clip". Since the creation and increased popularity of YouTube, mainstream artists now promote new music videos by releasing trailers of short promos on the site for their upcoming song and music video. Consequentially, YouTube has been converted into a social media platform for celebrities and artists to market themselves to their fans and audiences.

Apple stated at the WWDC 2015 that the service would launch at the end of June 2015 and would be free for the first three months of usage. After that, Apple Music subscription would cost US$9.99 per month, close to the economic equilibrium point for the recording industry estimated by the Open Music Model.
