Extremely sad to hear this news... we had the pleasure of meeting Zach earlier this year when he performed for us. Zach was just 18 years old and succombed to Osteosarcoma, a rare form of bone cancer, early Monday morning. He will be dearly missed.

The family has asked that all memorials be made to the Zach Sobiech Osteosarcoma Fund for Cancer Research found HERE.

(Mary Divine - Pioneer Press) Zach Sobiech died the way he lived -- with grace, strength, love and joy.

Sobiech, the Lakeland teenager whose song "Clouds" became an Internet sensation, died early Monday at his home, surrounded by family and his girlfriend, according to a CaringBridge post by Zach's mother. He was 18.

Sobiech, who had a rare form of bone cancer, began writing songs of farewell to family and friends last fall. His first song, "Clouds," went viral and has received almost 3 million hits on YouTube.

The celebrity driven site Soul Pancake recently made this video for Zach:

Sobiech, a senior at Stillwater Area High School, was told in June 2012 that he had months -- maybe a year -- to live. When a scan in October showed about 20 new lesions in his lungs, Sobiech's mom suggested he start writing letters to say goodbye.
