I run a choir for geeky kids. We try to find people like us that might appreciate music that we like. We perform songs from Adventure Time, Amazing World of Gumball, Dr. Who, Skyrim, Portal and other video games, anime and such. We are called Children's Choir of teh Internet.
Here is our latest little video of the Adventure Time theme song: https://youtu.be/AnIIVT3CbrA
We are planning to do a Marceline song later this year.
