Children cover Rammstein

[Video Link, and here's the original for comparison.]

Lots more on their YouTube channel. Uploader cartemarte1 explains:

Only 5 yrs and 8 mo, Cornelia is helping her older brother and sister to record one of their favorite songs. Rammstein has some amazing compositions, likeable to younger kids too.

Children Medieval Band:
Stefan (10) – vocal, guitar, violin
Olga (8) – keyboard
Cornelia (5) – drum, harp

The children have been trained with EarPower software.
