Find and take a photo of The xx (9/27) special edition Mirri posters posted around town. All original photos posted to Instagram will be entered to win a poster using hashtag #xxMarksTheSpot. One grand prize winner will receive a pair of tickets to the show and a pair of souvenir pint cups from SB Bowl. Hint: one is at SB Bowl.

One entry per account on Instagram—winners chosen at random.

Tickets are still available.
