“The Man Who Lived Underground” has a name. It’s Weaver, and he’s a poor electronics fix-it man drunk with insolent nostalgia who decries modern “upgrades” from his dingy urban catacombs. That’s the concept, anyway, via which Freaks Luke Solomon and Justin Harris revolt against dance industry vapidity and set stage for their curiously catchy production. Wrought with machinery effects and amusing audio theater, the tech-house on “The Man Who…” excels through episodes of bleepy motorized tension, plump dirty bass, and chaotic funk. The Freaks are pissed and want you to think before you dance, but this is great music even without the program notes.
