Vincent Peirani and François Salque, coming from two very different environments and musical traditions, have gradually developed languages and pathways of their own, involving written and improvised music as well as experimentations, from one concert to another. Their first disc, Est, was devoted to the traditional music of central Europe. This time their guiding thread is the music of South America, and more especially the universe of Astor Piazzolla. Their two sonorities, as magnificent as they are different, intertwine and interlace amid the melodic and rhythmic undulations of the pieces, sometimes adapted, sometimes created by Vincent Peirani, Jocelyn Mienniel, and Tomás Gubitsch.
