A maze, a phrenetic phone ringing, lift it and you fall into the ultimate maze – an erg – a sand sea. A mirage of three tents appear and to the side bedouins from another tribe cast shadows in sync with the dune soft songs, synths, cymbals, a reed instrument, pebbly percussion and tantalizing tape-loops perpetually merging like sand grains into dunes. Three versions of the event have been salvaged from the sand.
