Last month, "On the Download" premiered the first MP3 from Dirty Bombs, a Voltron-esque local supergroup featuring members of Televandals, the Luxury, and Conservative Man. Their collective mechanical roar persists here with "In Every City," a blistering post-millennial rock joyride that opens like an explosion, breaking at once into its electro-disco chorus before bouncing along through seas of fuzzed-out synths and thumps while maintaining a vicious alt-rock edge.
