The Mona Shores Singing Christmas Tree

Mona Shores High School in Muskegon, Michigan, constructs a singing Christmas tree for their holiday concerts every year for 31 years now. The tree is 67 feet tall and holds 240 of the 275 members of the world-renowned Mona Shores High School Choir. The tree also has 25,000 programmed lights, so it can perform on its own.

The first concert for 2015 was Thursday night, and performances continue the rest of this weekend. You can see more videos of the choir at the Singing Christmas Tree site. (via Metafilter)
