Rated R is the fourth studio album by Barbadian recording artist Rihanna, first released November 20, 2009, on Def Jam Recordings. The album is a musical distance from her previous effort Good Girl Gone Bad (2007), which contained up-tempo and ballad-oriented songs, and it heavily incorporated pop and dance-pop musical styles. Conceived after Rihanna's assault by her then-boyfriend, singer Chris Brown, Rated R features different foreboding and angry tone, in terms of musical and lyrical direction, and incorporates elements of hip hop, rock, and dubstep. The album also incorporated other musical genres, such as Dancehall in the Jamaican inspired "Rude Boy" and Latin in "Te Amo".
Recording sessions for the album took place during March to November 2009 at several recording studios throughout United States and Europe. Rihanna together with L.A. Reid, Jay-Z and Carl Sturken and Evan Rogers, executively produced the album and worked with several record producers, including Chase & Status, StarGate, The-Dream, Ne-Yo, and Brian Kennedy. The album also included several featured vocalists and instrumentalist, including Young Jeezy, Will.i.am and Slash who played the guitars in "Rockstar 101".
