Kingston’s Abyssinians emerged as reggae’s original Rasta conscience with their 1971 signature hit “Satta Massagana,” prior to Bob Marley’s international emergence. It’s Rastafarian liturgy, spiritual war music, invoking rebellion and prayer in the same breath. The title translates to “He Gave Praise” in Ethiopia’s official language, Amharic, and its booming bass and nyabinghi-flavored drumming formed hardcore reggae’s blueprint. Eightysomething original Abyssinian Donald Manning will be chanting down Babylon on Friday with a lineup featuring two of his sons providing rhythms, alongside Bad Brains vocalist H.R. and homegrown roots reggae-ists Lion Heights. – Tim Stegall
