I've seen some cool things at concerts...but this is awesome!! During a Foo Fighters show in the Netherlands Sunday, a meteor shot across the sky right over the stage. Someone thankfully caught it on video so we can all enjoy the view :)
One of the cool moments I remember at a concert was at Fiddlers Green. Stevie Nicks was on stage singing Dreams and right when she sang "Thunder only happens when it's raining..." the sky lit up with lightning. The timing was awesome.
