“N30: Who Guards the Guardians? by Christopher DeLaurenti fuses official and unofficial recordings of police transmissions made on November 30, 1999 into a weave of radio traffic, polyphonic speech, splashes and sprays of tape hiss and other broadcast anomalies. This radiophonic work depicts how law enforcement acted and reacted on that unforgettable day (referred to afterward by activists and law enforcement strategists as ‘N30’) in Seattle history when thousands gathered in Seattle to protest the World Trade Organization.”
