Green Day debuted a new track, which is titled 'Carpe Diem', during a live show in San Francisco - you can listen to it now on Gigwise.
The band performed the track, along with a selection of other new songs, during a secret show at San Francisco's Mezzanine venue on Tuesday (November 1).
Last month Green Day performed fifteen new tracks at a surprise last minute show for fans at the Tiki Bar 1700 Placentia in California last week.
The band, who are currently working on the follow-up to 2009's '21st Century Breakdown, played almost an entire set of previously unheard songs.
Among the new tracks were 'Nuclear Family', 'Carpe Diem' and '8th Avenue Seranade' as well as a cover of Ozzy Osbourne's 'Goodbye To Romance'.
