Catherine Ringer (from Rita Mitsouko) sings Müller & Makaroff (from Gotan Project) This is the story of two worlds sizing each other up, meeting and getting to know each other. On one side, the Argentinean Eduardo Makaroff and the Swiss Christoph H. Müller, the two pillars of Gotan Project, looking for extracurricular activities: to establish a bridge between tango and pop music, with original themes. To help them do this in style, a few female singers agreed to step out of their usual repertoire (rock? jazz? flamenco?). So they started to write for these singers and established a list of singular and prestigious vocalists outside of the world of tango. On the other side, Catherine, who in the recent years managed to impose the name Ringer, one of France.s great voices, who very serenely succeeded in building a career for herself after the Rita Mitsouko: after 30 years in a band that marked French rock forever with its peculiar style, she has bravely established herself as a solo artist.
