Reggae is a powerful cultural force that emerged from the streets of Kingston, Jamaica, during the 1960s and ’70s.

At the heart of its rise was the 7-inch vinyl single.

Massive sound systems — mobile DJ setups with huge speakers — would compete in public “clashes,” drawing large crowds and showcasing exclusive tracks. The 7-inch record, spinning at 45 RPM, quickly became the standard format for these events.

The 7-inch was inexpensive to produce, quick to press, and ideal for singles — short, punchy songs designed to move a crowd. Typically, these records featured a vocal track on the A-side and a dub or instrumental version on the B-side. This allowed DJs to “toast” (an early form of rapping) live over the rhythm — a key innovation that influenced both reggae and the birth of hip-hop.
