Zach was a teenager who found out that he had a rare form of bone cancer called osteosarcoma. It affects mostly teens and adolescents. After finding out that his diagnosis had turned terminal, he wrote a heartwarming song that has captured the hearts of people around the world.

The song is called 'Clouds'. He underwent many surgeries and chemotherapy, sadly the cancer spread out of control and it was found out that it had spread to his hips and lungs. At that point is when Zach penned the song and recorded. The song has been downloaded and shared and raised over $100,000.00 which has gone to research for the disease.
