ABBA finally unveil their super-realistic virtual 'ABBAtars' ahead of their upcoming Voyage concerts

After almost four decades out of the spotlight, ABBA are just weeks away from making their return to the stage with a series of revolutionary virtual concerts at London's Queen Elizabeth Olympic Park.

Thanks to George Lucas' special-effects company, Industrial Light & Magic, holographic versions of Agnetha Fältskog, Anni-Frid Lyngstad, Benny Andersson and Björn Ulvaeus will perform with a live 10-piece band in the purpose-built arena.

And now the beloved Swedish supergroup have finally released official images of their digital avatars - and they are impressively lifelike!

In the shots, the pop stars resemble their much younger selves and are dressed in '70s silver sequinned ensembles.

Fältskog can be seen gazing into the camera, with her blonde hair falling in a relaxed curl.

Fellow vocalist Lyngstad looks equally youthful with her trademark fiery red hair, a smokey eye and a simple nude lip.

Songwriter Ulvaeus shows off a freshly shaven face with his blonde hair styled in a shaggy bob.

While fellow composer Andersson's avatar sported a more svelte appearance, his blonde hair thick and bountiful.

The holograms have been created following months of motion capture and performance techniques.

ABBA originally split up in 1982 but reformed last year to release their ninth studio album Voyage.
