Diego El Cigala cut his teeth singing in the peñas and tablaos of ‘90s Madrid, collaborating with flamenco's top guitarists and dancers. In 1998 he launched a solo career with the album Undebel, with his gravelly voice and passion making him an emblem of the Romani gypsy tradition. His impeccable phrasing and full-throated delivery is always supported by superbly evocative musicianship, whether it's classical flamenco guitar and traditional percussion, or Bebo Valdés' Cuban piano—even big-band tango and salsa arrangements. Here is the best of this maestro's raw and authentic roots music.
