Musicólogo & Menes, also known as Los de la Nazza, is a Puerto Rican urban music duo formed in 2005 by Eliezer "Musicólogo" García and Eduardo "Menes" López. The duo achieved significant popularity in the Latin urban music field during the late 2000s and early 2010s as producers of Puerto Rican rapper Daddy Yankee, combining elements of reggaeton music with electronica influences. Musicólogo is Daddy Yankee's cousin.
The producers were joined as a duo by Daddy Yankee in 2007 and their first production credit was on his studio album El Cartel: The Big Boss, released later that year. Los de la Nazza continued working with Daddy Yankee until 2014, having produced songs including "Pose", "La Despedida", and "Lovumba".
Musicólogo and Menes began producing a series of mixtapes titled El Imperio Nazza released from 2012 to 2016. They turned independent in 2014, in order to focus on their own careers, and released their first studio album Orión in 2015.
