Emmanuel Gazmey Santiago, known professionally as Anuel AA, is a Puerto Rican rapper and singer. His music often contains samples and interpolations of songs that were popular during his youth. He is seen as a controversial figure in the Latin music scene for his legal troubles and feuds with fellow Puerto Rican rappers Cosculluela, Ivy Queen and Arcángel as well as American rapper 6ix9ine. Raised in Carolina, Puerto Rico, he started recording music at age fourteen and began posting it online four years later in 2010, before eventually signing to the Latin division of fellow American rapper Rick Ross's Maybach Music Group. His 2016 mixtape Real Hasta la Muerte was well-received, but his success was put on hold the same year by a 30-month prison sentence for illegal firearm possession in Puerto Rico. He recorded the entirety of his debut album while incarcerated, during which time his genre of music surged in popularity.

José Fernando Cosculluela Suárez, known professionally as Cosculluela, is a Puerto Rican rapper, singer and songwriter. In 2018, he was caught up in a controversy after fellow rapper Anuel AA released a diss track.
