Australian synth-pop quartet Cut Copy do the Eighties eerily well. Too well, in fact. Cue up the band’s third album, and you find yourself playing spot-the-influence. (That verse? So Depeche Mode. The chorus? Pure O.M.D.) Zonoscope opens with the New Order-like throb of “Need You Now,” followed quickly by “Take Me Over,” a spongy bite of Thompson Twins-style pop-funk. It’s impressive ventriloquism, and the songs are catchy. But the lovelorn sentiments are generic, and singer Dan Whitford’s baritone drone adds little to the proceedings. Relief comes when Cut Copy look back further: “Where I’m Going” adds some Spectorian grandeur to the band’s drum machine clatter. Then there’s “Sun God” — a 15-minute-long psych-synth opus whose delicious silliness almost wipes away the memory of the band’s slavish revivalism.
