You know that super sticky synthpop track with the youthful femme vocals cheering a rah-rah carefree chorus, “I don’t care, I love it!”? The one that’s oversaturated the airwaves and used in a range of places, from a Samsung Galaxy S4 commercial to Jersey Shore spinoff Snooki & JWoww (it was the theme song)? That’s Icona Pop, a duo made up of Swedish natives Caroline Hjelt and Aino Jawo; the rest of their songwriting is equally high-spirited and cheerful. New album This Is… Icona Pop, comes out in September. Warming up the stage on this date is K.Flay, the lady rapper-songstress from San Francisco with the husky-slinky flow style and a University education that lends an elevated level cleverness to her lyrics.
