The year 2008 is the occasion of an original collaboration between David and Grand Corps Malade for the title Si mon coeur, for his father’s album Ça ne ne sera finer. This collaboration has a sequel in March 2010 in the disc A new world of David. For this album, David composed all the music and played all the instruments. In addition to Grand Corps Malade, he notably called on Éric Chemouny and Pierre Dominique Burgaud. The first extract, We get scared, brings together David and his half-sister Laura Smet as a duo and quickly meets with success. Three weeks after its release, the album went gold. A second single Le Cœur qui can be released for the summer.
