Following an album whose considerably cleaner sound left their fanbase divided (2006's underrated Show Your Bones), this new EP returns to safer territory for the trio. Whether or not you enjoyed Bones, the brevity of Is Is highlights one of the Yeah Yeah Yeahs' greatest strengths: their ability to sound so big with so little. The drums and guitar are both rawer and stronger than in a long while and singer Karen O sounds positively primal at times, tremblingly tender at others. A quick reminder that despite more artful recent excursions, this band can still kick ferociously and without artifice.
