Welcome to listen to the many projects by Sound Quartet including BOP and more. We recommend that you buy or listen on triptychos.bandcamp.com, video on vimeo.com/soundquartet and if you must listen on Apple music or Spotify Bjelkeborn and Spotify Sound Quartet. We will asap move our music to plattforms that take responsibility for justified performing rights agreements and skip those who don't. The lucky few 1% of humans who owns the rest of us needs to step up their climate-care. Until they do we need to support more responsible music communities. Below follows a playlist on Soundcloud with older music, soon deleted.
