Last month, Bethany Cosentino of Best Coast hopped up on stage with Kendrick Lamar to guest on his song “No Make-Up (Her Vice)” and as unlikely as it was, Cosentino fit right in to the groove on Lamar’s track. The pair (and us) will always have YouTube, but we’re giving away a limited edition poster from the Uncapped performance, signed by both Bethany Cosentino and Kendrick Lamar.

In addition to the poster, Vitamin Water and FADER are throwing in an Uncapped tour t-shirt and a one-year subscription to FADER for the lucky winner. Here’s how to enter:
