Kaskade -- Aaaand Now Your Chicago Bulls' Starting DJ ... (VIDEO)

EDM superstar Kaskade is officially VIP with the Chicago Bulls ... mascot, anyway.

Kaskade got seriously swagged out by Bennie the Bull, and in a video the 44-year-old posted ... he was as giddy as any teenager would be. Makes sense -- he grew up in a Chicago suburb near where the Michael Jordan-era Bulls practiced.

In return, Kaskade gave Bennie a bunch of glow sticks and 2 tickets (for him and some cow) to the Ultra Music Festival.
