ABBA’s newest album titled “Voyage” will debut on November 5. Two new songs have been released ahead of the album launch — “I Still Have Faith in You” and “Don’t Shut Me Down” — which are available to stream on the band’s official website. Along with their big return, ABBA is preparing for a digital concert to be held at Queen Elizabeth Olympic Park in London. According to the band’s official statement, per Variety, the upcoming show is “the strangest and most spectacular concert you could ever dream of.”

The concert will be nothing short of the ordinary. Digital de-aged avatars were created for the ABBA members using motion-capture technology, and their likeness will then be projected onstage for the concert. According to a report from The Guardian, London Royal Ballet’s own Wayne McGregor created the choreography, and a team of 850 people worked on the special effects for the awaited spectacle.

Through the years, all four members have remained good friends, and they said they’ve been waiting for a while to work with each other again. When asked why they decided to reunite now when they are all in their 70s, Ulvaeus simply answered: “We wanted to do it before we were dead.”
