The singer-songwriter - real name Mike Rosenberg - surprised fans by announcing the one-off appearance on his official Facebook page just hours before.
The star drew in large crowds as he performed his global hit 'Let Her Go', as well as new song 'Scare Away The Dark'.
The clip features highlights from the eight-track set, as well as Passenger reflecting on his time busking before he became an international name.
The star will release his sixth studio album Whispers on June 9, as the follow-up to his 2012 breakthrough All The Little Lights.
The session was filmed exclusively for Transmitter TV, a YouTube channel that is updated with new music content daily.
