Ari Up, frontwoman of The Slits from the age of 14, died yesterday aged 48 after a long illness, it was announced by her stepfather, John Lydon of the Sex Pistols. The brilliant and confrontational female-fronted Slits were one of the finest examples of the punk era's DIY creativity, and also one of punk's most successful engagements with reggae. Ari Up never stopped being a fervent supporter of reggae culture in all its forms: after The Slits she formed New Age Steppers with legendary British producer Adrian Sherwood, and for many years she lived in Kingston, Jamaica where she was a keen participant in the local dancehall scene under the name Medusa.
