The FOO FIGHTERS performed in Iceland on Friday and DAVE GROHL brought his eight-year-old daughter Harper onstage to play the drums.

Dave said she told him two weeks ago that she wanted to play the drums, so he taught her.  The first song she learned was "We Will Rock You" by Queen, which is simple enough.  So the band played along to her beat. 

And she was fine for an 8-year-old beginner.  Of course, Dave started out as a drummer in Nirvana . . . so it's in her genes.
