Watch a video of Alog premiering a new, homebuilt instrument they will be using for upcoming performances: http://www.youtube.com/watch?v=krW_mFZwMKE
I know I've said it before, but Alog is one of my all-time favorite experimental/electronic acts and this is yet another good reason why. The instrument they build is called a "Slåttberg" and it's a strange digital/analog hybrid made to approximate the traditional Norwegian instrument, the Hardanger fiddle.
