Ricardo Arjona is among the most successful and best-selling Latin American artists of all time, with over 80 million records sold. He is often called El Animal Nocturno (The Nocturnal Animal), thanks to his breakthrough success with his fourth studio album, which bears the same name. His music ranges from ballads to Latin pop, rock, pop rock, Cuban music, and more recently a cappella performances, a mixture of Tejano music, Norteño music, and other Afro-American and Latin sounds. Arjona is noted for his lyrical style and often addresses topics such as love, sexuality, violence, racism, and immigration.
