Filled with smoldering ballads, intimate production, and openhearted sincerity, Ricky Martin’s 10th solo album is pure class. The singer can still deliver the kind of beat-driven smash that made him an international superstar, like the hard-grooving opener, “Adiós,” or Yotuel-assisted "La Mordidita.” But A Quien Quiera Escuchar is all about graceful, organic arrangements and Martin’s arresting sincerity. Acoustic guitars, swaying percussion, and jazz trumpet add glowing atmosphere to ballads like "Disparo al Corazón,” “Nada,” and "Mátame Otra Vez.”
