CMJ Music Marathon. If dreamy, ’80s-sounding indie pop is your thing, the Pains of Being Pure at Heart have your number in a big way. Close your eyes and this local quartet will whisk you away to a magical realm of Smiths posters and John Hughes montages. Portland performance artist and K Records signee Khaela Maricich sings sparse, charming electropop. Screaming Females are currently zooming up the local-band ranks, thanks in large part to the solar star-wattage of frontperson Marissa Paternoster, who boasts a righteous post-riot-grrrl wail and electrifying garage-punk guitar chops.
