SIGUR ROS and Belle & Sebastian have been announced as headliners for End of the Road festival in 2013.

The music festival takes place in the Larmer Tree Gardens, in north Dorset, from August 30 until September 1 and has been running since 2006.

The director and curator of the festival, 32 year-old Simon Taffe, is thrilled with the announcement: “Belle & Sebastian were one of the first bands we asked to perform when we started the festival and Sigur Ros are one of the best live bands around.

“I’ve seen them at other festivals and they’ve always blown my mind. Both suit End of the Road.”

The appearance by acclaimed Icelandic post-rock band Sigur Rós is one of just a few shows that the band will play in the UK this year.

The boys, otherwise known as Jón Þór ‘Jónsi’ Birgisson, Georg ‘Goggi’ Hólm and Orri Páll Dýrason, are known for their ambient, euphoric, sweeping soundscapes. Their name comes from Jónsi's sister Sigurrós.

Sigur Rós returned from a hiatus last year with their sixth studio album Valtari and a tour that included the biggest live show by an Icelandic artist in Rekyavik’s history.

Now, with further new music already creeping into their set, they appear to be taking on a harder, more electronic sound, pushing the boundaries of a genre they helped to create.

Many of their tracks have become ubiquitous through their use in films and TV, including the anthemic Hoppípolla from fourth album Takk… which was used in the BBC series Planet Earth, hosted by Sir David Attenborough. During their break, Jónsi also released a successful solo album and worked on the soundtrack to How to Train Your Dragon.

Sigur Rós are known for singing lyrics in a language called Vonlenska, which the band describe as “a form of gibberish”.

In 2010, Mojo magazine gave the band their Outstanding Contribution to Music award.

Sigur Rós’s three most recent albums – 2005’s Tak… 2008’s Með suð í eyrum við spilum endalaust and last year’s Valtari – have made the top 20 in the UK album charts.

Furthermore, four records from their back catalogue have been certified gold in the UK with second long-player Ágætis byrjun, released in 1999, going platinum in Iceland.

Organisers have also confirmed 12 other bands for next year’s event, including Palma Violets, Horse Thief and Angel Olsen. It was named 2011’s small festival of the year by the UK Festival awards. Tier 5 tickets are still available at £175 and are available from endoftheroadfestival.com
