Klangverkstedet is Anthony Barratt of Oslo, Norway.
About his music, he writes “inspired by tape music, collage and concrète techniques, I like using everyday sounds and other noises that are not inherently musical as the source material for my music making. The idea of creating music from the assemblage of disparate sounds and musical forms is a concept that I pursue.”
Here’s a link to a podcast he made for Cunei Media.
And, here’s some songs from bandcamp. I suggest buying them for ₤1 apiece if you like ’em. I highly recommend starting with “Henry the Horse.”
