The Chainsmokers brought their World War Joy tour to The Forum in Los Angeles this week for an exciting hometown show. Throughout the set, the duo exhibited unlimited energy and even had a surprise guest.

Toward the beginning of their performance, Drew told the crowd they had some surprises in store and, as promised, a little less than an hour in, they announced the arrival of a special guest: blink-182 as the team played their massive collab “P.S. I Hope You’re Happy.” The song features vocals from both The Chainsmokers’ Drew Taggart and blink-182’s Mark Hoppus, with additional drum sets from Matt McGuire and Travis Barker.

The lead member of the New York-based EDM group also took time to announce that their highly-anticipated album is due to be released next week. Stay tuned for more information on the drop of World War Joy and check out a clip from the live performance below.
