The online platform klingt.org for music and artistic activities beyond the side lines of mainstream has now been in existence for 17 years, and it is as versatile and active as ever.

Once a year, the community surrounding the server with the self-explanatory Viennese name that translates as “sounds harsh” has a big birthday party including a concert night that has virtually everything there is in store: from silent to loud, from soloist to bands, from electronics to analogue music, from beat to drone, from Vienna to Berlin.The live acts then blend into party and dance until the sun is high up, shining on a harsh-sounding new year of klingt.org.

Doors open: 8pm, program start: 9pm
