What is "grupera"

Grupera (or onda grupera) is a genre of Mexican folk music. It is influenced by the styles of cumbia, norteño, and ranchera, and reached the height of its popularity in the 1980s, especially in rural areas. The music actually has roots in the rock groups of the 1960s, but today generally consists of five or fewer musicians using electric guitars, keyboards and drums. Artists in this genre include Yonics, Los Humildes, La Migra, Los Caminantes, Limite, Ana Bárbara, Joan Sebastian, Los Temerarios, Grupo Bryndis, Marco Antonio Solís, Myriam, and Bronco. The music increased in popularity in the 1990s and became commercially viable, and is now recognized in some Latin music awards ceremonies such as Lo Nuestro and The Latin Grammy Awards.
