After the Portuguese Boom Festival cancellation, German Fusion is another festival to be postponed to 2022 due to the ongoing pandemic (and bureaucratic measures), while German ZEIT magazine quotes a study by World Health Organization WHO that the pandemic could have been prevented. Apart from few exceptions like New Fall Festival, that will be held as a seated “Summer Edition” (like in 2020) in the courtyard of NRW-Forum Düsseldorf, most summer festivals seem to have been cancelled already (as of May 2021):
