Last night, before M.I.A.’s set at NYC’s Terminal 5, Julian Assange Skyped into the venue from his current home in London’s Ecuadorian embassy. M.I.A. has had a long mutual admiration with the WikiLeaks founder, taking inspiration from him on her Vicki Leekx mixtape in 2010 and writing the theme to his The World Tomorrow program last year. Assange is also an uncredited co-writer of “AtTENTion,” on her new album Matangi, according to The Guardian. Watch the activist address M.I.A.’s fans below, and check out photos from the show above.

M.I.A.’s Matangi is out Tuesday via Interscope. Stream it here.
