Worlds Collide (also referred to as Worlds Collide Tour) was a concert tour co-headlined by American rock band Evanescence and Dutch symphonic metal band Within Temptation.[1][2][3][4] The tour was originally scheduled to begin in spring 2020, however, due to the COVID-19 pandemic and the safety measures that had to be subsequently undertaken, including the restriction of concerts, the tour had to be postponed. The first postponement occurred on March 13, 2020[5] and, as the pandemic persisted, a second occurred on June 22, 2020,[6] a third on April 13, 2021,[7] and a fourth on February 11, 2022.[8] With the safety measures lifted, the tour was able to start on November 9, 2022, in Munich, and concluded on December 8, 2022, in Berlin.
