You get this amazing Nirvana cover of epic proportions. 
The Rockin'1000 members gathered in one stadium in Cesena, Italy to perform 'Smells Like Teen Spirit' to a packed out audience of 15,000.
The 1000-piece band originally formed in July 2015 to perform 'Learn To Fly', a stunt to get the Foo Fighters to visit their hometown.
