Offered by Fr�meaux & Associ�s and For�ts et Campagnes d'Avenir, in partnership with the LPO (Ligue pour la Protection des Oiseaux), this 4-CD boxed set brings together the sounds of European birds captured and recorded by audionaturalist Jean C. Roch�, which are the closest to human monophonic music, right up to contemporary classical music. These songs reflect an incredible variety of melodies, rhythms and timbres, which, like the proto-languages of primates, can be considered the proto-music of mankind. An interview CD, recorded by Bernard Fort, founder of the GMVL, completes this collection. Jean C. Roch� talks about his fascinating exchanges and reflections on bird music with composer Olivier Messiaen. Patrick FR�MEAUX & Allain BOUGRAIN DUBOURG
