Coming out of the late 1970s with a harder twist to the vocal trio format, Israel Vibration used dissonant singing to get their socially conscious message across. Having met as sufferers at a polio institute, this trio knew what the hard life was about, often coming on stage with a variety of canes and crutches. Their capable backing is usually provided by the impressive Dub ensemble, Roots Radics, who lay down heavy rhythms for the sad falsetto harmonies and Bob Marley-like lead vocals. Is Vibes or I-Vibes (as they are known to staunch supporters) have one of the best live shows around, thoroughly entrancing their ganja-loving audience with tales of Jah, unity and culture, tightly packaged in one of reggae's most haunting trinities.
