The piano is a quite versatile instrument and essentially a percussion by itself; percussion is per se a universe of possibilities, at times a keyboard in itself. The invention on emission and interaction modes may generate variably dis-concerting situations – therefore exploring the instruments of the three pieces may help us to briefly outline the sound scenarios. The programme chosen by Beneventi and Rebaudengo summons a wide choice of instruments but somewhat coalesced in strong characterizations (metal - skin - wood). Composers and pieces offer a live and unexpected image of the “specialty” of this duo, and represent the tout-court compositional invention of France and Italy from the last decades. If we join the nationalities with the origins (Jewish-Moroccan and Greek for the French Ohana and Aperghis, and Lecce, Southern Italy, for Fedele), a nice geometrical figure can be drawn in the Mediterranean Sea; perhaps the eloquence and expansiveness of their musical pieces, so different from each other, are the result of this common background. In brief, the interpreters, once having conceived and recorded the album, have themselves composed a thoughtful and evocative piece.
