Book excerpt: Bringing the same incisive, cross-genre perspective he offered in When Rock Met Disco, Steven Blush gives a spirited survey of the crossover of Jamaican, British, and American sounds that changed the face of popular music in When Rock Met Reggae. The inspiration of ska, rock-steady, dub, and reggae—heard on independent recordings played on “soundsystems” from Kingston and Brixton—created a new rock tonality and attitude, spanning from Eric Clapton to The Clash. Meanwhile, the “Two Tone” sounds—traversing The Specials, Madness, and UB40—fueled the ‘90s ska revival of Sublime, No Doubt, The Mighty Mighty Bosstones, and beyond. Attentive to the racial, political, and artistic aspects of this intricate story, Blush gives a memorable account of one of the most fertile cross-pollinations in pop music history.
