Sound Clash Explained

A sound clash is a contest between sound systems: crews take turns playing to the same crowd, and the crowd's response decides who wins. Selection, exclusive dubplate specials and the MC's delivery decide it. The form dates back at least to 1950s Jamaica and is a fixture of reggae and dancehall wherever the culture travelled, including Britain.

Origins

Jamaican sound systems competed for the same dancers from the start. Clashes go back at least to the 1950s; the first reported one was between Tom the Great Sebastian and Count Nick in 1952, and Tom the Great Sebastian also clashed Duke Reid's Trojan in Kingston's Back-O-Wall district. Rivalry ran high enough that some clashes turned violent.

In Britain, clashing became part of Black British sound system culture. Jah Shaka was running sounds and clashing in London as early as the 1970s, and Franco Rosso's 1980 film Babylon centred on the London scene. More in our UK sound system history.

How a clash runs

Formats vary by event. A common structure:

1. Round one: each sound plays a set time. No one goes out.
2. Elimination rounds: with more than two sounds, one is knocked out each round, for a weak showing, poor sound quality or playing a back-up tune, until two remain.
3. Shrinking slots: time per turn gets shorter as the night goes on.
4. The final: tune for tune, or "dub fi dub": each sound answers the other one dubplate at a time. In one common format, the last ten dubplates decide it regardless of who led earlier.

The crowd is the judge, through noise and "forwards", a surge towards the front. Many clashes also have rules on content: traditionally every dubplate must carry the sound's name, and replaying a riddim already used in the clash can cost a sound the contest.

Dubplates and specials

A dubplate is an acetate disc, usually 10", originally cut by studios to test a recording before mastering and pressing. Sound systems took them up to play music nobody else had. A special is a one-off version of a tune, re-voiced by the artist with lyrics that name and big up the sound, made to win clashes. Sounds have paid artists for exclusive use.

A deep box of specials from respected artists is the strongest hand in a clash, and a plain release played against a special rarely wins a round. See dub and the sound system.

The MC

The MC is the sound's voice in a clash: introducing each tune, setting up why it beats the last, taunting the opposition and working the crowd. Sharp delivery can carry a round. See selector, operator and MC.

Does the bigger rig win?

Not on its own. Where all sounds play through one house system, it is selection and presentation. Where each sound brings its own rig, sound quality counts: poor sound is grounds for elimination in the format above, and a system that stays clean and heavy at volume beats one that is louder but breaking up.

That second case is hard on sub drivers: hours of long, deep basslines at level test coil heat handling and excursion. The mechanisms are in voice coils and heat and Xmax and excursion. For scoops and folded horns, the WM18X451 pairs a 115 mm copper coil and double spider with an 1800 W RMS rating, at £345.

Safety

Clashes pack crowds tight against the stacks. Secure stacks, keep the public off boxes and cables, give the crew hearing protection, and leave power distribution to a qualified person. See loading and stacking safely.
