This is Mason on the new guitar he got for Christmas, Carter singing, and Trevor playing drums/sound effects with his mouth, during a family gathering over the Christmas holidays. They figured out the cords/words/arrangement by listening to the song. I love those boys!
1/14/14 - I've added another video of the boys singing, "Radioactive".
Radioactive, performed by Mason (guitar) Trevor (voice beat box) and Carter (vocals) (using microphones in guitar and bass amps :) on 1/12/14
Radioactive, (can't hear very well) (Christmas holidays)
