PURITY RING, BLUE HAWAII
(Roseland, 8 NW 6th) Shimmering, crystalline bubbles of sugar-synth emit from Purity Ring's carefully crafted lullabies. The Canadian duo's enveloping hiphop-pop perfectly captures the zeitgeist of the right now, and their inventive light show is captivatingly, strangely beautiful. NED LANNAMANN


MAPS AND ATLASES, YOUNG MAN, HUSTLE AND DRONE
(Mississippi Studios, 3939 N Mississippi) Bands with a penchant for math and angularity don't always endear themselves to listeners, but Maps and Atlases seem to have figured it out on their most recent album, Beware and Be Grateful. The album is one of abundance, with constant surprises among the angular guitars. Neat little loops and layers rise and fall, only dawning on you after you've been listening to them for a few minutes. But good songs aren't built on cool tweaks, so it helps that Maps and Atlases can write a melody. It doesn't hurt that Dave Davison sounds an awful lot like Kyp Malone—sincere, soulful, and smart all at once. But unlike TV on the Radio, no song ever feels half-assed. Is there too much going on? Some songs feel a bit cluttered, but there are no throwaways here. REBECCA WILSON
