To celebrate the release of Mosh Pit Imperial this week, DJ Brian Engel will be spinning some tunes from noon-5pm on Saturday in the Beer Hall. But that’s not all.

Bring your own vinyl. Ask him to play a track off it. If he selects yours, we’ll comp you a flight of all three Mosh Pit beers (Hazy, Juicy, Imperial), a $12 value. To increase your odds, bring something good instead of something bad. We’re sorry if this is how you find out the truth about Jason Aldean.

(Needless to say, must be 21 to participate.)
