This is the piano reduction of a work which in its turn is an extension of "Remebrances of Poland II", a dramatic piano piece of a Slavic character, for solo performance, now orchestrated for film orchestra, to which a slow introduction was added that I wrote in 2010, plus some fast and agitated measures that I created in the same year under the title "La grande mélée". Hence the current title of this composition: "COMPLICOMPOSITIO IV: Une grande melée".
