Let It Go brass quintet

The Lopezes wrote this song for Disney's 2013 animated film, "Frozen." It immediately became a worldwide hit and a favorite of little girls (some big ones, too) everywhere. There are recorded versions in at least 41 languages. It won the 2014 Oscar for Best Original Song, among many other awards.
