With their name appearing on seemingly every festival line up ever this summer, it was almost inevitable that Thee Oh Sees would join the ranks. Idles, who release their debut album today, will also be performing at the event.

Soulwax, Car Seat Headrest, Foxygen, Parquet Courts, Yak, The Moonlandingz, Temples, and The Orwells complete the new additions, joining the likes of Interpol, PJ Harvey, Mac DeMarco at the festival's 27th edition.

The Jesus And Mary Chain, Ty Segall, Angel Olsen, DJ Shadow, and Black Lips have also been previously announced to play.

Taking place in the idyllic setting of St. Malo, France, the festival boasts stages located on the beach, and in the awe-striking ruins of the Fort Du Saint Pierre.

La Route Du Rock takes place from 17-20 August. Event details can be found on the website. Ticket packages are on sale now.
