The Vocal Art Ensemble digs deep into the salt of the earth, excavating the cultural foundations that shape the ever-flourishing art of song. Cultivating choral transplants across countries and generations, VAE nurtures a musical garden of human experience, through the common grounds of life, death, faith, serenity, love, and dreams.
 Collaborating in this program will be ceremonial sound practitioner René Jenkins, who uses ancient indigenous instruments to harvest timeless soundscapes of magical dimensions.
