The name grupera comes from the fact that many of the bands had names starting with Grupo (Group).[2]Most of these groups had a rural origin and many previously played rock music. According to Madrid, cited by Rivera Godina,[2] the grupero movement had its peak in the 1970s with many famous artists who were included under the label tropical music, such as Mike Laure, Rigo Tovar, Chico Che, among others, both Mexican and from other countries, who fused romantic ballads with more danceable rhythms, such as Los Baby's, Los Freddy's, Los Corazones Solitarios, Los Pasteles Verdes, Los Barn de Apodaca, and Los Caminantes.Under the influence of the music and film industries, the most well-known norteo bands became synonymous with grupero.[3]
