Cumbia sonidera, Mexico's highly danceable version of cumbia, is the pulse of the country's streets. It exploded in popularity in the early ‘00s, with synthesiser and accordion uniting to carry its catchy melodies and guacharaca-driven beats keeping bodies moving all night long. “Sueño Contigo”, by Mexico City godfathers Sonido la Changa, embodies the classic sound; permanently lovelorn poblanos Chicos Aventura incorporate a touch more lyricism. In the underground, groups like Sonido Gallo Negro have fused surf rock and other Afro-Latin rhythms to sonidera, while others, such as Afrodita, spin it into new electronic subgenres.
