Led by Heddy Boubaker, the Toulouse-based band has created a sound that defies categorization, blending elements of free jazz and psychedelic afro-latin rhythm, and more to create a truly unique musical experience which they self described as "post-pfunk-afro-voodoo-weird-free-rock". With 'Au nombre de joie' and 'Le bonheur des uns fait le malheur des autres', the ÈCH make up two little gems of music that take us back to a time when every note, every instrument was carefully thought out, down to the last detail, a time when music was made simply right. The EP's artwork, created by painter, trumpeter and percussionist Walkind Rodriguez, represents with colors and shapes blending together to create oneiric flames, archetypal symbol of the band's soul, whose name is derived from a Hebrew word meaning 'fire'.
