Mumford & Sons, James Blake and Roisin Murphy have joined the NOS Alive festival, alongside headliners Muse, Gigwise reports.

The 55,000 capacity Portuguese festival takes place in July at the centre of Lisbon (running 4pm-4am each day) and will feature a headline performance by Mumford & Sons. The event takes place 9th-11th July, meaning anyone keen to check out Marcus Mumford and co. before their Reading Festival appearance would be well advised to get an Easyjet flight.

Other new additions to this year's lineup include Roisin Murphy (who will be hopefully playing tracks from her new album Hairless Toys) and James Blake (similarly showcasing his hugely anticipated new LP Radio Silence).

Ben Harper & The Innocent Criminals and Australian electronica specialist Flume are also taking part. Other acts on the bill include Alt-J, Metronomy, Kodaline, The Jesus and Mary Chain, Jessie Ware, Young Fathers, The Ting Tings, The Wombats and Dead Combo.
