múm (pronounced [muːm], “moom”)** is an experimental Icelandic pop group whose music is characterized by soft vocals, eccentric beats and colorful effects, and a variety of traditional and unconventional instruments.
múm have never walked the well trodden path. Since the the beginning of múm, they have always gone their own way, the way their creativeness and their music has been excessively difficult to pin down and anticipate. Originally a duo, the band has expanded and contracted like a beating mammalian heart in the 12 years of being and has counted 15 – 20 people along the way.
