Worlds Collide (tour)

The first time members of both bands met was at an Evanescence concert in 2018, which led Amy Lee to dig deeper into Within Temptation songs.[7][8] Following a festival in Switzerland that both Evanescence and Within Temptation co-headlined on the same day, the two bands agreed that planning a tour together would be a great idea.[9][10] A few weeks later, both bands posted teaser clips on their respective social medias regarding an undisclosed project, creating some buzz for a possible tour or musical collaboration.[11] On September 17, 2019, it was announced that they would embark on a tour together in April 2020, passing through seven countries in Europe. According to both Lee and Sharon den Adel, a collaboration between them was something the public of both bands had been asking for a long time.[2][7] The two bands developing a good personal relationship was another element that led to the conception of the tour, as Lee pointed that her and Den Adel "instantly connected" the first time they met.[7][8] Regarding the title of the tour, Lee stated that both bands chose it together. According to the singer, although they live in very distant countries and have some differences in their music, they also share a lot of similarities, so the name reflects well the embracing of both.[7]

A few days after the beginning of the sales an extra concert in Amsterdam was added, as the first one had already sold out.[12] On October 29, five more dates were announced due to high demand and fast selling tickets. Three United Kingdom extra dates were added as the London one had sold out, so as one in Belgium, and Luxembourg also entered the route.[13][14][15] Due to the COVID-19 pandemic, both Within Temptation and Evanescence decided to postpone the tour with rescheduled dates to be announced for fall 2020.[5] The tour was then rescheduled to start on September 2, 2020, passing through the same cities.[16] By May 2020, a total of 150,000 tickets had already been sold.[17] As the pandemic persisted and the occurrence of concerts was still prohibited, the tour was postponed again for September and October 2021.[6] During the outbreak, members of both bands took part at the Together at Home movement, where artists make online live performances from their houses to encourage people to stay home and prevent more infection cases by respecting social distancing.[18][19]
