Improv Everywhere, the group behind the infamous No Pants Subway Rides, is at it again, and if their past “missions” are any indication, then this year’s seventh annual Mp3 Experiment is sure to cause a scene. In its six previous installments, groups of strangers have been turned into cohesive units through music and the voice of narrator Steve pumped through participants’ mp3 players. Games of Simon Says, conga lines, and friendly battles have erupted seemingly out of nowhere—to the bewilderment and hilarity of bystanders. This year, the experiment will take place today somewhere in Manhattan—in true Improv Everywhere style, the mission is shrouded in secrecy until the day before (October 1) when location details and the mp3 will be released on their website.
