Build a didgeridoo

Silvia and Kees both know exactly what they are talking about when it is about building and playing the didgeridoo. They have been discovering the secrets of this beautiful and inspiring instrument for years. Originally, the didgeridoo is an Australian wind instrument. For centuries the Aboriginals have been playing and using this hollow tree for their spiritual traditions. With this instrument, they tell stories about their lives and those of their ancestors. Because these stories are unknown to us, we play this instrument in a western way. We are inspired by the moment and by the music of the other person. From this joint hobby, Airflow was born. This name covers everything that matters when playing the didgeridoo: Air bending in different ways with our own body as the main instrument. With Airflow we want to inspire others to meet this beautiful instrument. We do this by demonstrating how the didgeridoo is made and of course by playing the didgeridoo, with explanation how these beautiful sounds come to life.

Historical Medieval Battle

Real steel, real weaponry, extreme battles. This is full contact medieval combat. This is Historical Medieval Battle.

Historical Medieval Battle is a relatively young sport in which contestants battle each other in full armour, with real (blunt) weaponry in an effort to defeat each other much like they used to in the Middle Ages in tough combat. Contestants fight full contact and about anything is allowed to make sure the opposing fighters are downed. Fighters train hard to get better, travel the world to fight and train and compete every year in the ultimate showdown, the world championships HMB; Battle of the Nations.

NLD was also represented at Battle of the Nations, they fought hard battles alongside the United Kingdom, and won Bronze in the Mass Battles category 21v21.

Come and hear the sound of crushing metal, feel the strength of real warriors and smell the atmosphere of medieval battle at Castlefest!

The Fae and Pagan folk band SeeD taps into the mysterious world of the Ancient Fae and the modern world of dreams and passions in life.

Their aim is to make these two separate worlds converge, thus activating people in making the best of both. The four musicians travel from festival to festival to inspire the people lost in this world and to tell the listener tales of the vast Fae realms, or to simply get everyone dancing to the energetic, self-composed Pagan folk tunes.

SeeD plays music of their own creation. Every single one of the band members helps with composing and writing the music, thus creating an organic flow of creation. Because of this, there is not just one kind of song in their repertoire, but a healthy mix of all kinds of Pagan Folk tunes and songs.

SeeD plays on Thursday and Saturday at Castlefest.

Erik Betten (Leeuwarden, 1976) is historicus en journalist en heeft een reeks boeken geschreven over geschiedenis, het landschap, kunst en cultuur. Hij schrijft zowel in het Nederlands als in het Fries. Quarantaine, over de nasleep van een bacterie-uitbraak bij gasboringen in Groningen, is zijn romandebuut. Een spannende, actuele thriller met het Noord-Hollandse landschap in de hoofdrol.


Songs about ancient magic, the wisdom of nature and the ecstasy of dance. Energetic and wild at some times but also spherical and dreamy are the sounds rolling of the stage. But yet the binding theme of old myths and legends remains, their power and secret reverberating in the music of the band to this day.

On historic and modern instruments they combine their own compositions with influences from european folk-music. Danceable rhythms intertwine with catchy melodies and arrangements for up to three voices enchant the audience.

In 2018 WALDKAUZ look back to a five year experience as a touring and performing band, nationally and internationally. Among past events and festivals are Wacken Open Air, Wave Gotik Treffen and Autumn Moon Festival. So, this year WALDKAUZ is going to pursue new ways and giving a special jubilee show: No less than three guest musicians (Fabienne and Fanny from Brisinga, Andi from Faey) will accompany the band for an even more powerful and mystic perfomance!

Waldkauz plays on Sunday at Castlefest. This show will be only accessible for Castlefest camping guests.

‘A wonderful initiative!’

Two thousand years ago the Celts were driven off of mainland Europe. All Celts? No, one band bravely resisted the influx of modern pop and rock and found their own place in the world of music.

Armed with nothing but their voices and instruments, Rapalje is raiding clubs and halls far and wide, looking for victims to carry away on a musical journey through Scottish Highlands, Irish valleys, taverns and inns.
Ground shaking jigs and reels, delicate ballads and a whiff of heavy metal provide you with the perfect opportunity to not care about everyday life.

Ladies and gentlemen, let’s dance…

Rapalje plays on Thursday at Castlefest


Sowulo creates modern day Viking Folk-music, that is inspired by pagan culture.

Their ritual music will take you on a inner journey. Their acoustic music will let you celebrate our great pagan legacy. The aim of this musical project is to create deeper awareness of our spiritual heritage. This is brought forth by beautiful ambient conceptual music, and by the opening ritual at the start of Sowulo’s concerts.

Sowulo’s first album, Alvenrad, was built upon the pagan year feasts, expressing the four seasons. The follow-up, SOL, is an acoustic album which contains a tasteful blend of new and old material, recorded with acoustic instruments exclusively. Again, the main theme of the album are the cycles that are created by our beloved Sun. However, the songs on this album are more earthly and uptempo.

Be sure to take a listen to this exceptional band!

Sowulo plays on Friday and Saturday at Castlefest.

Adrian Stone

Not many bands can lay claim to the kind of dramatic career development that the Icelandic band Árstíðir can. Formed in the wake of the 2008 stock market crash, they found themselves catapulted to the top of the Icelandic music charts within six months of their debut, and then forged ahead with their 2010 tour despite a volcanic eruption that stalled global travel.

Árstíðir’s music defies genre borders and might best be described as classically influenced indie folk rock. Whether in a train station in Germany, a concert hall in Russia or a bar at home in Reykjavík, theirs is music that mesmerizes audiences. The band members’ wide range of musical backgrounds and experience, combined with professional interests ranging from law to literature and engineering to computers, make them unique in their wholly democratic approach to music making and performance. Entwining the elements of sound with lyrics describing heartbreak, longing, memory and a deep connection to the circular oneness of life, they marry organic acoustic traditions and modern electronic arrangements with intricate simplicity and unpretentious skill. 

At the end of 2017 Árstíðir toured Europe together with Sólstafir and Myrkur. In March 2018 their new single ‘While This Way’ came out, from their upcoming fourth album ‘Nivalis’, that will be released at the end of June 2018.

Árstíðir plays on Saturday at Castlefest.
