short for "sound system," i.e. a DJ collective, sometimes mobile. roots in jamaican culture, particularly dub or dancehall. a sound consists of selectors and deejays. the selector spins dubplates through usually massive wattage, and may be accompanied by the deejay, who will chat over the tunes. rival sounds may challenge one another, in a soundclash. the winning sound is said to "kill" the other sound.
ring the alarm, another sound is dying. woa-oh, hey.
