Polish festival that draws the world's biggest names in music from around the globe.
Radiohead's Jonny Greenwood, rapper Nas and José González' new band Junip have been added to the line-up for this year's Open'er.
It's not the first time the guitarist has appeared at the festival on a Polish airbase - last year he performed with composer Krzysztof Penderecki.
This year he will be performing Electric Counterpoint - a 1987 electric guitar composition by Steve Reich, which is divided into three parts: Fast, Slow and Fast.
Queens of the Stone Age, Blur and Arctic Monkeys are all on this year's bill.
Heineken Open'er takes place July 3-6 2013 at Gdynia-Kosakowo Airport in Gdynia.
