On their self-titled sophomore album Sky Eats Airplane manage to fuse metal, hardcore, and electronica without recalling dated industrial rock from the 1990s. The Houston, Texas quintet has forged their own "electronicore" sound that leans hard on screamo trappings with vocals that approximate glass gargled shrieking, before segueing into more melodic ascensions. Chunky guitar riffs contrast nicely against harmonic leads playing over sternum rattling bass and mechanical beats that come off less like a drum machine and more like the firing of heavy artillery. A hearty lineup change in 2007 gives Sky Eats Airplane a much darker and heavier tension than anything on 2006's Everything Perfect on the Wrong Day. Here, Jerry Roush's singing pulls off a Jekyll and Hyde bipolarity sounding like a man half possessed by demons one second and impassioned angels the next. "Numbers" erupts with tantrum heavy howls before Roush inflects self-harmonized melodies loaded with the kinds of barbed hooks that give this song instant hit status. An opposite approach is taken with the similarly catchy "The Artificial" as it begins with easy-on-the-ears melodies before breaking up into throat-burning bursts of rageful rasp.
