Destiny has merged with electronic nation and could totally afford him but I have a feeling ink might have a leash on him.
Wemf has turned into digital dreams, I believe.
Electronic Nation is Live Nation. Ryan from Destiny works for Live Nation now.
INK is the promoter of record for Deadmau5 and gets first rights. They also have a partnership in Veld Festival, so it is only natural that they work together on other events. The show at the Rogers Center was a partnership between INK and Live Nation.
Digital Dreams is a partnership between Live Nation and other parties, including Capture (group that owns Maison, Century Room, Kiwi, Hamman Spa..) and Uniq (group that owns Cinema, Brant House, Jacobs & Co...).
