Combining the former guitar player from hardcore band Poison the Well with a former Nickelodeon star, Sleigh Bells is the most aggressive, poptastic, ear-drum-splitting glamour-thrash band around. On its debut, Treats, released on M.I.A.'s N.E.E.T. Records, Sleigh Bells offered up songs like "Rill Rill" and "Tell Em" that managed to rock the cranium while melting the heart. This February saw the band's Saturday Night Live debut, perfectly timed with the release of the album Reign of Terror, and the act killed the audience with its hopelessly infectious "Comeback Kid." If you've somehow managed to miss out on the wonder that is Sleigh Bells, take a moment out of your lunch break to view the video for that song. We guarantee that when it ends, you'll be asking yourself if you have time to watch it again.
