Yeah Yeah Yeahs’ billowing cloud of avant-rock is invaded here by a clutch of disco synths, exploring new areas of tempo, personality and atmosphere for this New York art-punk trio. Guitarist Nick Zinner steers the course with imaginative guitar work, drummer Brian Chase probably hasn’t had this much fun drumming on a record before, and singer Karen O wraps herself in electrical-taped chiffon for disco drag-outs “Zero,” “Heads Will Roll” and “Dragon Queen.” Production from David Sitek (TV On the Radio) and Nick Launay ensure It’s Blitz! is a contemporary affair.
