Hadal Zone, written by composer Žibuokle Martinaityte for bass clarinet, tuba, violoncello, contrabass, piano and electronics, seeks to plumb the lower ranges of these instruments, shaping a listening environment that is defined as much by sound and vibration as it is by the musical intent of the composer. Performed by the adventurous Lithuanian ensemble Synaesthesis, and featuring recorded samples of the San Francisco-based choral group Volti (conducted by Robert Geary), the hour-long work takes it's title from the scientific name for the region of the ocean that extends below 6,000 meters, where sunlight can never reach. ATTENTION: please remember that all Blu-Rays are Region A USA and all DVDs Region 1 USA and you will need a multi region Blu-Ray/DVD player to play them.
