As original members of UB40, Ali, Mickey and Astro helped to define reggae music for a generation. The multi-racial band, formed in 1979 in the Birmingham suburb of Moseley, pooled a diverse set of influences to put a fresh, indigenous slant on Jamaican reggae. After encouragement from Chrissie Hynde, who offered them support slots with her chart-topping band The Pretenders, they recorded their independently released debut album, Signing Off, on an eight-track tape machine in the home of producer Bob Lamb. An unexpected number two album, it gave them the conviction to chart their own course.
