*2024 stock* Alfred Wolfsohn was inspired to explore such questions about vocal range after serving in the World War I. Haunted by cries on the battlefield and suffering from post-traumatic stress, he began experiments as a form of therapy. Alternating between vocal and instrumental (including piano, violin, viola, cello, and double bass) exercises, Vox Humana not only showcases the potential vocal range of the human voice, but also the various expressive timbres and tone qualities that can be utilized. His experiments push the range of the human voice to nine octaves (two more than the piano!) and demonstrate an impressive, avant-garde flexibility. Liner notes include an introduction and track notes.
