Martyn is one of the main movers in dubstep, a spectral dance music sound that works as a moody, meticulous update of both jungle and drum 'n' bass. Where most dubstep goes dark and dystopian, Martyn proves comparatively spirited, even uplifting at times. He's Dutch, which may have something to do with it. But regardless, his 2009 album, Great Lengths, ranks highly on a very short list of significant dubstep full-lengths, and his range of styles leave him lots of room to explore. Martyn covers much of that range on a striking 2010 mix-disc called Fabric 50:Martyn.
