Yet our sounds are also a vocabulary for those who detest the walled-off concentrations of wealth, and steal property back: the collectives that build their own sound systems, stage free parties, and invite DJs to perform. The international DJ becomes emblematic of global capitalism’s complicated cultural dimension. On flights and at the free Continental breakfasts in hotels, often the same soul-destroying hotel chains in each city, we get stuck chatting with our fellow Americans and Western Europeans, the executives eager to find compatriots. We make small talk with these consultants and deal-makers in the descending elevators in the evening—then go out to the city’s dead-end and unowned spaces or its luxury venues to soundtrack the night of the region’s youth, hungry for something new. DJ music is now the common art form of squatters and the nouveau riche; it is the soundtrack both for capital and for its opposition.
