WWE has placed Braun Strowman and Elias in a unique match.
A couple weeks ago, Braun Strowman used an orchestra bass as a tool of mockery and a weapon against Elias. The two had just been in the Elimination Chamber together and Strowman decided he wanted Elias to "get these hands." Then last week, Strowman and Elias had a match which ended in Strowman chasing Elias out of the arena.
Today, WWE announced Strowman will be meeting Elias in a "Symphony of Destruction" match. Mike Rome said via the WWE twitter that not much is known about the match except the symphony part will benefit Elias while the destruction aspect will benefit Strowman.
Neither Strowman or Elias have a clear opponent for Wrestlemania 34 since losing their chance at Brock Lesnar by not winning the Elimination Chamber.
