Back in August 2011, Madonna took a long holiday in the south-west of France and visited different locations in the Basque Country.
When visiting Guéthary, Madonna met Basque trio Kalakan who played for her during an intimate birthday gig with friends and family. They got introduced by the Labèque sisters, whom Madonna refers to as her “favourite pianists in the whole world” in the “I’m going to tell you a secret” documentary.
For the upcoming MDNA Tour, Madonnarama already revealed that “Open Your Heart” will be featured on the setlist. We can now report that Madonna will be working with Kalakan to create a new, revisited version of “Open Your Heart” that will feature “Sagarra Jo” by Kalakan.
