Amazon.comMasters of the entire Latin music lexicon--from Cuba to Argentina--the members of this Boston-based sextet hail from various outposts in the Spanish-language world, giving their mesh of traditions the cohesion of a single original vision. The sound of Sol y Canto (Sun and Song) is natural, not a collage, and it draws its deep soul from husband-wife founders Rosi and Brian Amador. Lead vocalist and bongo-percussionist Rosi possesses a delicious buoyancy that easily encompasses the heartbreak of Nueva Cancion ballads and the sparkle of up-tempo dance tunes. Musical director-harmony singer-writer-arranger-acoustic guitarist Brian lays a warm, detailed framework by applying classical and flamenco guitar techniques--using plastic strings, an unusual choice--to Latin American forms. A host of stellar vets contributes to this airborne set, which soars highest when Rosi articulates the many shades of sadness and yearning, with Brian's sensitive harmonies shadowing her leads amid a nest of acoustic strings, finely drawn percussion lines, and trilling flutes. --Elena Oumano
