Culture is widely acknowledged as the greatest roots reggae harmony group of all time; they made acclaimed records and toured widely for thirty years until lead singer Joseph Hill's untimely passing. Two Sevens Clash is hailed as one of the greatest, most influential records ever made; the title track's predictions brought the city of Kingston, Jamaica to a standstill on the fateful date of July 7, 1977, the day when the "7's" would fully clash. The album was an important influence on a whole generation of punk rockers including The Clash and The Sex Pistols.
