One great music maker that people haven't heard of much is Fredrik Thordendal, formerly from the band Meshuggah. His solo album "Sol Niger Within" (Or "Special Defects", to name the english version) is simply awesome. It doesn't fit in any genre tho, it's something very abstract and atmospheric, a combination of guitar, bass, drums, keyboards, violin, sax, and other instruments - it's got a unique sound...

I don't have a link right now, just Google for it.
