So a bunch of italian foo fighters fans wanted the band to play in italy where they haven't played since 1997 so they did what anyone would do ... organise a 1000 musicians and play a cover of Learn to fly in an attempt to attract the bands attention and get them to come and play a concert.
It's a pretty crazy stunt and a pretty good cover considering the number of people playing so maybe they will get their wish it's got 14m views so maybe one of those is one of the foo fighters :D
