Long stretches of Al Viento sound like a virtuosic flamenco guitar player has decided to sit in and play complement to a beautiful performance of Bach’s Cello Suites. This music is knotty but light—something difficult rendered approachable by the way it’s presented. Pedro Soler and Gaspar Claus—father and son—do their work with wood and string the way other fathers and sons do their work with hammer and nail or block and beam.[BUY Al Viento]
