Markedly different in style from his previous albums, Poquita Ropa was produced using as few musical instruments as possible. Arjona's goal was to produce the songs "almost as they were born"; he achieved this by using nonexistent sounds to make the songs sound more acoustic. Arjona achieved a production style that made the songs sound like a capella performances, and he said that "music and women look better with little clothes."
As of 2014, Arjona had released fourteen studio albums, one live album, nine compilation albums and forty-three singles. His work earned him numerous awards and accolades, including one Grammy Award, one Latin Grammy Award, and a "Latin Trajectory of the Year" Award at the Orgullosamente Latino Awards of 2010.
"Marta" is a Latin pop song recorded by Guatemalan recording artist Ricardo Arjona. It was released on 29 March 2011 as the third and final single from his twelfth studio album, Poquita Ropa (2010). It was written by Arjona, who produced it with longtime collaborators Dan Warner and Lee Levin under their stage name, Los Gringos. An accompanying music video for "Marta" was released in March 2011 and features Mexican actress Edith Gonzalez. It was directed by Joaquín Cambre. The video was used as part of the feature film Poquita Ropa — Una Historia Apasionada.
