The origins of KJ Sawka are unclear—it's said that this human/drum hybrid was first encountered after a meteor collision in the Nevada desert. Now he calls Seattle home and makes music as inscrutable as it is unmistakable: liquid synth washes; dubby, reverbed samples; and shape-shifting beats perfect for jacking dance floors. Cyclonic Steel, Sawka's second LP, came out last week, further documenting the development of this evolutionary anomaly. (Neumo's, 925 E Pike St, 709-9467. 9 pm, $8, 21+.)
