Avenged Sevenfold is having a lot of fun in 2017. Not only have they announced new U.S. dates with Metallica, but they’ve recently confirmed their own headlining dates this Summer as well. To gear up for the upcoming tours in the States, the guys are currently performing across Europe, and as you’ll see in the video below, they are enjoying every moment, both on and off the stage.

After their recent set in Helsinki, the band was partying at the Hard Rock Cafe, and decided to jump on their stage and perform for the restaurant. The guys grabbed the house instruments, and played a hilarious and very tipsy version of ‘Nightmare’ that you must see!
