American indie rockers Warpaint, British newcomers Daughter and electronic rock band Bastille have all been added to the line-up for the Heineken Open’er Festival 2014.
The bands will join the already impressive bill alongside previously announced headliners Phoenix, The Black Keys and Pearl Jam.
Poland’s largest open-air music festival will take place from July 2-5 in Gdynia.
Last summer’s festival was headlined by Arctic Monkeys, Kings of Leon and Queens of the Stone Age and this year’s line-up looks set to be equally as exciting.
Tickets are on sale at Opener.pl/en with more artists to be announced over the coming months.
