Rihanna’s Open’er Bonus

Rihanna is to perform what amounts to a free concert in Poland July 7, a day after the award-winning Open’er Festival ends.

Fans who bought tickets for the four-day event on the Gdynia-Kosakowo airfield will be allowed free entry to the Rihanna show.

Those who bought camping tickets will be able to stay another night at no extra cost.

Those who missed the Alter Art-promoted festival will have to fork out between euro 48 and euro 62 to catch the Barbadian star.

The festival lineup includes BlurKings of LeonArctic Monkeys, and Queens of the Stone Age

Rihanna’s performance is a nod to her recent seventh album, Unapologetic, which she promoted with her 777 Tour, playing seven shows in seven countries over seven days.

She’s also reportedly flown the whole jaunt in a Boeing 777.

The other acts on Poland’s biggest  outdoor fest (July 3-6 ) and winner of Europe’s Best Major Festival award in 2009 and 2010 include Maria Peszek, Animal CollectiveTame Impala, and Disclosure.
