Too often regarded as a footnote to proper reggae, dub can be a rich style in its own right. The 22 newly unearthed 1970s dubs from master mixer King Tubby on Bring the Dub Come provide dazzling proof. Adapted from singles by singers like Dennis Brown and Big Youth, these danceable instrumentals exist in a state of constant flux, with leisurely horns, clattering percussion, and clanging guitars bubbling to the surface and then disappearing abruptly, as in a dream. Liberal reverb and massive, pulsating bass lines add to the surreal vibe. Far from a collector's obscurity, this is a musical experience that's guaranteed to raise a smile.
