Foo Fighters fans got an extra-special treat while at the Secret Solstice Festival in Reykjavic, Iceland.
Dave Grohl began to introduce an 8-year-old to the stage, but it wasn't just any ordinary kid... It was Grohl's 8-year-old daughter - Harper. Not only did she make an on-stage appearance, but she also was the lead-drummer for a cover of Queen's "We Will Rock You".
It's safe to say that Harper Grohl has the genes to ROCK!
