Witness the amazing Chris Avantgarde at Het Sieraad on Saturday, February 15. Being back on our stage is an intimate gig for the German who is rocking arenas and stadiums from Vegas to Ibiza as an Afterlife bigshot.   German duo Avalan Rokston is also storming the big stages and might create even more of a momentum with their cinematic beats and Avalan’s exhilarating live vocals.
