We put out the holiday call and you answered. Dozens of musicians entered for a chance to perform at the third annual Colorado Matters Holiday Extravaganza. We'll announce the winner on Friday, but for now, we're showcasing a few of our other favorite contenders.

The three Downey Sisters—Cate, 17; Ella, 14; Meg, 10—from Denver wrote and performed a mashup of their favorite holiday songs. Warning: you aren't going to be able to get 'I Want A Hippopotamus For Christmas" out of your head.
