Duval collaborated with Ensemble Ethnique, to realize, for the record "Somewhere Else", the following pieces:

- Apho
a song in the Ebriè dialect of Cote d'Ivoire, where gripping rhythms melt with symbiotic vocal melodies

- Angele
a prayer dedicated to his mother, sung by Duval himself, in Ebriè dialect, the black sound melts unexpectedly with the origin, when there were songs about freedom in afro-reggae style.


- Santiago
L'ukulele, Afro-Cuban percussions by Alfredo Verdini and the great influence of "Salsa", mark this extraordinary song.
