Green Day, Weezer and Fall Out Boy want to prove that rock acts can still pack out stadiums.  All three acts have teamed up for a 2020 stadium tour. Here are the numbers. All three bands together have averaged 27,000 ticket sales per show. The average stadium holds 30,000.  To promote the 2020 tour, each band will release new music.  The idea of all 3 bands touring together was propelled by Crush Music who manages all three acts.  Ironically, none of these bands have embarked on a stadium tour. If the tour is a success, then Green Day, Weezer and Fall Out Boy can walk away boasting big numbers increasing their star power in todays over-saturated musical climate. “The world is super hip-hop- and Instagram-[oriented], and I think this is counterprogramming to all of that,” says Wentz. “This is the biggest rock’n’roll thing that’s going to happen that summer.”
