M'um are an Icelandic band. Saw them at the Medicine Bar in May 2002. Unfortunately, a lot of the audience had turned up expecting something different, and so talked throughout the gig - (expletive deleted).
If you're a pigeon-hole fan, then Electronica is a good label. They had some sort of Moog synth, a computer, one of those plastic thingies with the little keyboard which you blow though (perhaps they had two thingies like this), plus various other instuments including guitar played with a bow.
Good gig!
