Monchy Y Alexandra

Monchy & Alexandra were a bachata musical group from the Dominican Republic. They sang together as a duo beginning in 1999. Their first big hit was "Hoja en Blanco", which they released in 1999. Since then, they had many other hits, such as "Hasta El Fin" and "Perdidos", both from their 2004 album "Hasta El Fin", as well as "No Es Una Novela" from their 2006 "Éxitos y Más" album. They have been often credited with being instrumental in popularizing bachata music outside of the Dominican Republic.
