ABBA Voyage is a virtual concert residency by the Swedish pop group ABBA. The concerts feature virtual avatars (dubbed 'ABBAtars'), depicting the group as they appeared in 1979, and use vocals re-recorded by the group in a Swedish studio specifically for this show, accompanied by a 10 piece live instrumental band on stage. The concerts are held in ABBA Arena, a purpose-built venue in the Queen Elizabeth Olympic Park in London.
