The Bottle Boys, or Flaskedrengene as they are known in their native Denmark, don't use conventional instruments.
They prefer beer bottles.
In 2008 they competed on a Danish talent television show.
And make adorable youtube videos.
They rock out on bottles all year round...
...and attract some great crowds.
Look at them pulling off amazing selfies with ease.
In their free time they flash mob grocery stores.
Can you imagine the amount of beer they drink? For the instruments of course.
They are pretty much the cutest thing Denmark has ever produced.
