Esmark, named after a glacier at Spitzbergen that debouches into the Ymerbay, is a collaboration between the sound architect Nikolai von Sallwitz (Taprikk Sweezee, Karachi Files) and the experimental artist Alsen Rau (Scheich in China, On+Brr). Both have worked on various experimental and performative projects together since 2001. Esmark's musical setup is mainly build analog. Instruments like drum computers and synth boxes have been connected in constantly changing chains of fx and filters. Some recorded on tape and fed back into the compositions.
