Mastodon/EODM or UFC 211. . Choices.

I just purchased tickets to go watch Mastodon perform live with Eagles of Death Metal in Chicago May 13th, and now I Realized UFC 211 is the same night. WTF do I do?

Go to the show and avoid results of the UFC until after you get to watch it?

Don't know mastodon but if it's your thing, then go 

211 is a bad ass card though. It's hard not to be excited for it.

Are they playing the night before somewhere within 6 hours?

Stream it when you get home
