It’s Blitz! by Yeah Yeah Yeahs

Karen O and company are back. It's Blitz! by Yeah Yeah Yeahs ($11) takes the band in the world of electronica, with a start that mixes hard guitars equally with soft synthesizers, a middle that returns to more straight forward rock, and a soft, reflective closure. Buy the album from iTunes, and you'll also be treated to acoustic versions of four of the album's best tracks, along with a bonus track.
