After battling bone cancer for three years, Minnesota teenager Zach Sobiech was told this past May that the disease had spread and that there were no longer any effective treatments available. In response to this disheartening diagnosis, Sobiech embraced music as a way of bidding farewell to his friends and family. The resulting song, titled "Clouds," is an inspirational and courageous message of hope in the face of a harrowing future. You can hear Sobiech's "Clouds" and learn more about his story on YouTube.
