Mimi and Josefin are just 13 and 15 years old and they had everyone of the judges on 'The Voice: Kids' in Germany on their feet. Watch the reactions of the judges and the crowd when those voices come of these little girls. And the harmonies...don't even get me started on those. I'm a sucker for great harmonies. Watch and be amazed.
The talk afterwards is obviously in German, and it doesn't seem to have subtitles, but you don't really need to speak German to understand what's going on.
