One of the best things about the whole Buena Vista Social Club phenomenon is it has provided a template for world-music impresarios to pluck masterful, aging players out of regional obscurity and successfully bring them to a huge and affluent audience. And they can do it, too, without watering the sound down into Westernized, electronicized pap. Indeed the authenticity of these playerstheir retro aesthetic, their decades of insulation from the corrupting influence of the more developed worldis a big part of how theyre marketed. Sometimes I get a little cynical about the formula. But not when it helps promote brilliant players like Jose Manuel Cobles (stage name: Puerto Plata) and Edilio Paredes, two giants of Dominican guitar. Cobles also sings, beautifully. Their sextet, with electric bass and three percussionists, captures a hundred different Latin influences, with music thats danceable, wistful, lascivious, and virtuosic at once. Theyve been getting new exposure through the efforts of Benjamin De Menil, a Putumayo veteran with a Harvard MBA.
