Foals and MGMT added to Open'er line up
Foals and MGMT have been announced as joining the line-up for this year's Open'er.
The festival takes place in Gdynia in Poland 2-5 July 2014.
When Foals played Open'er in 2011 the show was so intense their guitarist's fingers bled.
Pearl Jam, The Black Keys and Phoenix are already on the bill.
Tickets are on sale now.
