Two brothers, Lars and Martin Horntveth, form the core of this very talented ensemble. Although they've seen a lot of faces come and go, they always manage to keep together a solid lineup that can not only hang with their old stuff, but help inspire new material. Both brothers (and pretty much everyone else in the group) are multi-instrumentalists, and its interesting to see how their dynamic changes as they switch up instruments or just push the limits of their main ones. So, even if you're not entirely familiar with Norwegian experimental jazz rock, there's plenty of other reasons to give this great musical project a listen.

Got any favorite multi-instrumentalists?
