An amazing troll job by Deadmau5 towards Martin Garrix.
The history:
In January:
1. Tour for Martin Garrix is announced on Twitter.
2. Deadmau5 replies asking if he was going to play "Animals."
3. Garrix replies to Deadmau5 asking "Did Old MacDonald have a farm?"
The result? This amazing troll job by Deadmau5, who replaced Avicii (in hospital) at Ultra tonight....
