Placebo, Duffy and The Ting Tings, have become the first acts to be confirmed for the 2009 edition of the Heineken Open'er festival in Poland.

Madness, Gossip and Buraka Som Sistema will also be playing the event that takes place from 2-5 of July in Gdynia.

A four day ticket for the festival will set you back 320 Polish Zloty, which is approximately £61.

Last year the Open'er was headlined by the likes of Bjork, Chemical Brothers, Muse and The Beastie Boys.
