Emanuel Herrera Batista, better known as El Alfa El Jefe (or simply as "El Alfa" or "the Boss"), is a charting, influential Dominican rapper. He is regarded in his home country as one of the most influential in dembow (a Dominican hybrid of dancehall and reggaeton). Since 2012, he has issued more than three dozen digital singles and videos, including the early hits "Muevete Jevi" and "Tarzan." His YouTube videos have garnered hundreds of millions of views. Using his thin, gritty voice in syncopated phrasing, his trademark rapid-fire rhymes are regarded by fans as being as infectious as his beats. His recordings are staples on Latin urban stations across the U.S. and Caribbean; he has been a featured performer in one of WSKQ-FM's (Mega 97.9), sold out Madison Square Garden revues, and collaborated with artists ranging from Farruko to Cardi B to Bryant Myers. His 2018 sophomore album, El Hombre, hit number six on the Top Latin albums chart.
