In the early 2000s, in Mexico the term Regional Mexican began to be used. Regional Mexican music had already been used for several years in the United States to refer homogeneously to the regional variations of rural Mexican music and avoid including tropical music artists under the label. Meanwhile, grupera came to refer specifically to the bands and solo artists that use electric guitars and basses, electronic keyboards and drums, but that played ballads, cumbias, rancheras, corridos, boleros and huapangos, with said genre being one of many styles under the Regional Mexican umbrella.
