 The album includes " Fuiste Tú " , a duet with Guatemalan singer Gaby Moreno . Its instrumentation consists of piano , violin , guitars , drums and other percussion . Although Arjona stated that he " had the possibilities to record this song with very well known people " he expressed his happiness with Moreno , revealing that " the possibilities of doing it with her , for me , are a celebration " . He described Moreno as " incredibly talented " , a " countrywoman " and a " fantastic human being " . Arjona named " Fuiste Tú " as one of the most important songs on the album . " Mi Novia Se Me Está Poniendo Vieja " took two years to complete and Arjona dedicated it to his mother , Noemí Morales .

As with his single " Señora De Las Cuatro Decadas " ( on 1994 's Historias ) , at first he never thought to include the song on an album . " Caudillo " evokes " the image of some friends " Arjona had at college ; he asserted that he " appears constantly there because sometimes we transform ourselves into a contradiction of all those things we fought in those moments . It 's the history of a student leader that becomes a president " . Arjona dedicated the album to his father , who died in 2011 .
