Gotan is tango spelled sideways. On their 2001 debut, this Paris-based Argentine-French-Swiss trio smoothly subverts the seductive syncopated sound of Buenos Aires with suave electronic beats and brooding atmospheres. Their blend of disco-length originals and head-turning covers by artists like tango icon Astor Piazzolla ("Vuelvo al Sur"), Frank Zappa ("Chunga's Revenge") and Gato Barbieri ("Last Tango in Paris") invite us into a world where the bandoneón concertina and violin meet DJ culture on the dance floor, with sublime results.
