(MUSIC) Shout Out Louds is an appropriate name for a band whose praises should be sung from the mountaintops. On their debut LP, Howl Howl Gaff Gaff, the Swedish noisepop act ties you to their helium balloon hooks, sending you soaring through a romantic mélange of melodic styles and harmonies that will make fans of bands like the Concretes and the Arcade Fire swoon. Even Howl‘s crestfallen moments are buoyed by instrumentation so full of hope there’s no room for moping around. (Crocodile, 2200 Second Ave, 441-5611. 9 pm, $10.) JENNIFER MAERZ
