Green Day are amongst the latest additions to the line up of Optimus Alive.
Hosted in Lisbon, Optimus Alive is fast emerging as one of the continent's top live music events. Cheap flights from the UK are connecting more and more British fans each year, with work well under way on this summer's instalment.
Green Day are set to headline Optimus Alive, emerging from slumber after Billie Joe Armstrong's much publicised onstage outburst last year.
Preparing to get back out on the road, the American punk group will top the bill at the Lisbon event. Elsewhere, Editors are set to take part with acclaimed 4AD signing Twin Shadow also due to perform.
Scottish rockers Biffy Clyro recently completed one of the most ambitious albums of their career, and the Ayrshire trio will toast 'Opposites' at Optimus Alive.
Other new additions include Mercury nominees Django Django, with Phoenix, Of Monsters & Men and alt-j all due to take part.
Tickets are on sale now, as a bonus for fans the organisers of Optimus Alive have teamed up with TAP Airlines to offer festival goers a 10% discount on their flights.
Optimus Alive runs between July 12th - 14th.
