Paris' coolest pair of cybernetics perfects its robot rock on Discovery, morphing Homework's buzzy filter disco into an even suppler strain of electro-funk. Never shy of lite-FM cliches, they turn guilty pleasures into unabashed house anthems with "One More Time" and "Digital Love," and give the vocoder a passionate workout on the infectious "Harder, Better, Faster, Stronger." Throughout, the synths go to 11 and the vocals beam down from cloud nine. Establishing one of the decade's most durable sounds, Discovery paved the way for everyone from Justice to Kanye.
