Bands are changing their sound quicker and quicker. Point in case: While Sleeper Agent's breakthrough single "Get It Daddy," which is only 3 years old, is catchy as hell, the sound was definitely more in the camp of The Strokes than Passion Pit. But trends tend to have sway on young bands, and while the release of "Waves" could have turned out to be a cash-grab modification to the band, it seems genuine and sounds pretty damn good. Go ahead and try to listen to this without it getting it stuck in your head.
