The songs which are part of this CD, bear the mark of the great, eclectic Maestro Alessandro  Alessandroni. These songs were composed for the broadcast of eight episodes made by RAI  -Department of School Education for Adults or D.S.E. - called: “OPEN  WINDOW". It was  directed and organized by the RAI director Marco Procopio and the included reports related  United Europe and the countries that were part of it.  Four of these interesting episodes, filmed in Italy, Spain, France and Germany, were the first  part of the show. The CD title “INCHIESTA” ("Investigation") is already explicit.   The song “INDAGINE” ("Inquiry"), is a "slow" interim in which the theme of a soft blown flute  and one of the first monophonic synthesizers fits a delicate harmonic range of voices, a base  of bass, drums and electric guitar work. This simple and well designed song offers the listener  a calm atmosphere, but never sleepy, which sharpens the faculties of thinking of someone  who is collecting the various  informations for investigations.   “LA METROPOLI” ("The Metropolis") offers a glimpse of the place where, potentially, occur  criminal episodes. It is a violent and percussive song in which horns along with percussion  emphasize the harshness of the place. “IL PORTO” ("The Port"), by contrast, is set in a quiet,  sleepy and lazy place, where everything is motionless except for the pitching of the boat.  Another song, in contrast with the previous one, is “IL CORRISPONDENTE” ("the  corresponding") where the music points out, in a constantly and swirling tonal and rhythmic  movement,  the frenzy of a reporter who must frantically chase news, before someone steals  them to him. Musically astute and finely ironic is the song “IL COLLETTIVO” ("The  Collective") where the voices of the vocalists are superimposed on one another in a fun and  rhythmic counterpoint, imitation of the overlapping of voices coming from an agitated meeting  at which everyone wants to have their say, obtaining at least in this case, a perfect harmony  of purpose. Maestro Alessandro Alessandroni, with these compositions, has got the meaning  and essence of the word "investigation" , musically describing the situations, concepts,  places, and characters with his professionalism, his experience, and the great genius that have always distinguished him.
