The oriental philosophy and the Pa Kua, or Trigramas, basic symbols of the forces of the nature, inspire the sounds of the musical piece that was performed for the first time this Wednesday in the Gran Salon of the Provincial Council of Badajoz. A concert included in the Badajoz Philharmonic Society's VIII Cycle of Contemporary Music, in which the Arriaga Trio has also performed pieces by Granados, Casablanca and Gerhard.
