Aswad is arguably Britain's most successful reggae band, in terms of both popularity and longevity. Critical opinion of their body of work is often divided. Some hail their early material as the greatest roots reggae Britain ever produced, beginning with their 1975 self-titled debut, which highlighted the plight of the immigrant Jamaican in the unfamiliar and often hostile environment of '70s London. Others find their later pop-crossover phase more distinctive and unique, when they shifted to funk and soul, resulting in the U.K. chart-topper "Don't Turn Around." Regardless, Aswad's ability to adapt themselves to the changing times – new musical trends, shifting personnel – was ultimately the driving force behind their decades-long career.
