For their third full-length studio album, "It's Blitz!," New York's Yeah Yeah Yeahs found inspiration in unlikely places: the disco dancefloors of the '70s. The lead single, "Zero," takes its cue from Donna Summer's "I Feel Love," a pulsating, hypnotic bundle of sexual energy that popularized the synthesized backing track. With emphasis on keyboards instead of guitars, Karen O, Nick Zinner and Brian Chase bring an irrepressible excitement to the track that alternative radio programmers are embracing. TV on the Radio's David Andrew Sitek and Nick Launay—the producer behind the intense, richly textured songs on the group's EP "Is Is"—expertly guide the band's new synth-heavy direction without losing the eccentric charm that made it an indie rock favorite.—Alexandra Cahill
