Juan Luis Guerra y 4.40 (Dominican Republic)

Juan Luis Guerra is a Dominican singer, songwriter, and self-producer who has sold over 20 million records worldwide and has won numerous awards, including eleven Grammy and Latin Grammy Awards, and two Latin Billboard Music Awards. He won 6 Latin Grammy awards in 2008 in the same night which ties him with Juanes to hold the record for most Latin Grammys won in one night. 
He is one of the most internationally recognized Dominican artists in decades past. His pop style of merengue and bolero and Afro-pop/Latin fusion have garnered him considerable success outside the Dominican Republic. Juan Luis Guerra is sometimes associated with the popular Dominican music called bachata, and while this association is partially true, he actually uses the basics of Bachata rhythm with a more bolero feel to the melodies in some of his songs. He does not limit himself to one style of music, instead, he incorporates diverse rhythms like merengue, bolero-bachata, balada, salsa, rock and roll, and gospel. "Ojalá Que Llueva Café" ("If only it would rain coffee") is one of his most critically acclaimed self-written and composed pieces. A remix of "La llave de mi corazón" ("The key of my heart") with Taboo from the Black Eyed Peas is also an example of his fusing of different genres.
