Jaga Jazzist is a band from Norway with post-rock song structures but instrumentation and harmonies that draw mostly from the worlds of jazz and electronica. I first caught wind of them by sampling the beautiful track "Swedenborgske Rom" from What We Must. I was an immediate convert and listened to that one track probably 40 times in the first week I had it. Their other two albums are weirder and less aerial but have hundreds of interesting nooks and crannies to explore.
