Slowblow is an Icelandic musical duo consisting of Orri Jónsson and Dagur Kári Pétursson. Their music is an aesthetic of home-made, lo-fi analog tinkerings, which often slips into both electronic and folksy terrain. They began recording in the mid 1990s and have made several albums together. They created the soundtrack for the successful independent Icelandic movie Nói Albínói, which Dagur directed, and have worked with other Icelandic artists such as former Múm band member Kristín Anna Valtýsdóttir. In 2009 the duo provided the music to the film The Good Heart. They have released albums under the Reykjavík based record labels Smekkleysa, Kitchen Motors, and Mobile / Plug.
