What draws drummers out of their basements and singers out of their showers? What requires miles and miles of XLR cables and hundreds of microphones? Rockin’1000! The brainchild of rock-aficionado Fabio Zaffagnini, the event invites musicians of all experience levels, genders, sexual orientations, classes and creeds to jam out in Florence, Italy. It’s no easy feat to get 400 guitarists, 250 drummers, 300 bassists and 350 singers to rock as one, but with a collective passion for music and a hearty dose of logistical wizardry, the show goes on.
