World music isn't a term anymore. Like "global south", the label is reductive and meaningless, suggesting anything outside the North Atlantic pop and rock hegemony is similar. Times change, and the hegemony collapsing, with Latin America's industry now the biggest on the planet and South East Asia giving it a run for that money. Nevertheless, we're struggling to think of a more appropriate category for Africa Express' latest. After all, when you take artists from four continents and get them to collaborate with open-ended aims, the record becomes a global thing. 19 years after it was founded through the joint efforts of Malian titans Toumani Diabate, Bassekou Kouyate and Amadou & Mariam, alongside Damon Albert, Martha Wainwright and Fatboy Slim, Africa Express remains groundbreaking and far-reaching. This instalment recorded in Mexico during the Bahidora Festival - a renowned platform for experimentation - the results are awesome.
