Calling Girl Talk’s Gregg Gillis a “mash-up DJ” is a little like saying that Pablo Picasso liked to paint. Girl Talk’s aural kaleidoscopes churn through samples at such a dizzying speed that Feed the Animals sounds like an all-night dance party crammed into 54 minutes. The juxtapositions are sometimes intentionally absurd, as when he segues from Eminem to Yael Naim’s “New Soul” (that Feist rip-off from the Apple AirBook ads). More often–as when he crams snippets of Big Country, Kraftwerk, Hot Chip, The Cardigans, “Planet Rock,” and “Whoomp! (There It Is)” into one dizzying 30-second sequence–it’s just some of the best party-starting music ever engineered.
