“‘Monsoon’ means change. It’s the song that changed our lives completely,” said Bill.

“When we decided to make a new version of ‘Monsoon’ the idea we had was to make an acoustic record, let’s arrange it with an orchestra and do something nice with the 2020 version but it just felt boring. We had to do something special for 15 years of this track that started it all for us.” adds Tom Kaulitz.

“With ‘Monsoon 2020’ we are celebrating the past, taking it into the present, embracing the future and creating a time capsule of the last 15 years of Tokio Hotel. The LA based director Kris Moyes (who also directed the epic video for ‘Girl Got A Gun’) had the amazing idea to use my body as a screen and project all these memorable moments of the band onto me. It’s not only about us and our past, it’s also about all of us as a whole and the world we live in, in 2020… how the world changed and how we have to change with it! ‘Together we‘ll be running somewhere new’ – it’s hopeful and nostalgic,” Bill says.
