When Buenos Aires native Eduardo Makaroff and Swiss born Christoph H. Müller met in Paris during the creation of Gotan Project in 1998, they both already have a rich musical career background, in their countries of origin as well as in France.

Alongside their activities within Gotan Project they have written and produced together music for feature films, documentaries and advertising. From their soundtrack of the movie « El Gaucho » by Andres Jarach, they created in 2008 an album of the same title, their first release as « Müller & Makaroff. »

With Gotan Project in 2001 they released « The Revancha del Tango », « Lunatico » in 2006 and in 2010 « Tango 3.0, three albums which were big international successes. Many of their songs were used in movies, TV series etc..

Three world tours with Gotan Project later, the association « Müller & Makaroff » takes a new dimension with « Reencuentro », a clip and a short film initiated by Renault and directed by Pablo Giorgelli (award winner at Cannes Films Festival).

In 2014 Catherine Ringer (from french cult band « Les Rita Mitsouko ») joins them to sing their new Tango Pop songs. The result is an album: PLAZA FRANCIA « A new Tango Songbook » released by french label Because and another big tour in France and Europe. PLAZA FRANCIA has been playing major festivals and venues in 2014 & 2015.

In 2018 they release a second album in the Plaza Francia series, a musical evolution from Plaza Francia to Plaza Francia Orchestra, with guest vocals from Catherine Ringer and Cape Verdean diva LURA.  2018-2019 they tour with a new band including Volco & Gignoli, and Maria Muliterno on vocals. The tour ends in November 2019 in Abou Dhabi.

In October 2020 M & M  release the first track of their new project ANTROPOCENO! feat. Fémina, Hilda Lizarazu & Mia Folino.
