The sleepy, southern Norwegian town of Tønsberg – the oldest town in Norway – is currently bracing itself to host an event which, each summer, turns the otherwise tranquil setting into a hive of musical activity.

Each July, Slottsfjell Festivalen returns to the waterside town to bring an excellent and inventive line up to a crowd of avid music fans, with every corner of the town getting involved in the festival in some way. An old, disused warehouse will once again be transformed into a midnight melodic haven for late night revellers to experience DJ sets and performances from the likes of Totally Enormous Extinct Dinosaurs and Sweden’s Elliphant, whereas the boardwalk along the water that surrounds the tranquil town will throng with music fans making their way through the town to the various events.

But the real action will be happening on the festival site, where the organisers have invited the likes of Kendrick Lamar, Susanne Sundfør, Hot Chip and Alt-J as well as Best Fit favourites Chad Valley and to perform on the stages dotted around the event’s idyllic setting.

Whether they’re playing in a caravan on a hillside, under the bright lights of the festival’s main stages or atop a (fairly large) hill, in the looming shadow of the Slottsfjellet (a tower erected on the site of a Viking fortress which once stood in its place), the festival site is a perfectly selected spot to inspire unique, memorable performances – as proven in recent years by unforgettable shows from Röyksopp, Grinderman, Mogwai and Deerhunter.

As well as world renowned headliners, a host of other acts – international and home grown alike – will be taking to Slottsfjell’s scenic stages, including the likes of Dan Deacon, Daughter and Norway’s very own Jonas Alaska.

And never an event to limit itself to a singular genre, crowds can expect to see performances from acts such as emerging Norwegian electro-duo Lemaître, Sweden’s The Tallest Man on Earth, Norway’s excellent Truls and Brits Dan Croll and Tom Odell too. An inspiring line up and a superb setting hint that Slottsfjell 2013 is destined to once again be an unforgettable event, and one certainly not to be missed.

Slottsfjell takes place in Tønsberg, Norway on 18-20 July – head to the festival’s website for more information.
