The BBC, which has so much music on its website that one could get lost for a month in its holdings, only to find them replenished anew the month following, has posted a massive catalog of the WOMAD 2004 festival. Now, much of this is “world music,” albeit with the occasional electronic touch, residue of founder Peter Gabriel’s work in that arena. But there is some more discernibly “electronic” work to be heard, notably a percussive, hour-long set by DJ Dolores, of Brazil, listenable to in streaming form here.
