MGMT and Rudimental will also play at the Polish festival.
As per usual, Open'er is due to go down at the airport just outside the coastal city of Gdynia. There will be five nights of music, beginning on July 2nd and running through until the 6th. Bashmore joins a rock-heavy bill, topped with stadium fillers like Pearl Jam and Foals. There are a few others pushing electronic sounds, though, with Phoenix, MGMT and Rudimental all set to make appearances. So far, Bashmore is the only act confirmed to play the Beat Stage, so it's likely a few more names pushing house and techno are on the way.
