Juan Carlos Calderon (1938-2012) was a composer, producer and arranger Spanish. He combined his work with his jazz band.
"The name of this outstanding musician is tightly attached to the best jazz sessions recorded in Spain during the mid-60s and early 70s, although his huge commercial success was gained through writing and arrangements for extremely popular Spanish artists such as Massiel, Joan Manuel Serrat or Mocedades to name but a few. His first steps into jazz at the legendary Drink Club in Santander, opened by his brother Ramón in December 1959, where he created the Santander New Orleans Jazz Band, were followed by regular performances at the Whisky Jazz Club in Madrid, where he settled down a few years later, sharing stage with all the top jazzmen of the local scene. His first two albums, are essential milestones in the Spanish modern jazz history, stepping into a later period of his career where the artist would incorporate elements of fusion sounds under the influence of funk, disco or even flamenco music" (Javi Bayo).
