In Jamaica in the 1950s and ’60s, locally produced music (American R&B covers, ska, then reggae) rarely made it onto the radio because it was considered inferior to what was being produced abroad. Instead it was common for homegrown music to be played over large sound systems in public spaces. Over time this practice became as much a part of reggae as the music itself; it is supposed to be heard over large sound systems. Without that conduit, many aficionados believe, you lose something. When Carter Van Pelt was wandering along the Coney Island boardwalk four summers ago, it dawned on him: the open space, the lack of nearby residences, the built-in audience made it a perfect place to play reggae the way they do in Jamaica.
