First roaring out of the New York underground in 2009, Sleigh Bells are the unlikely duo of hardcore punk guitarist Derek Miller and former teen-pop singer Alexis Krauss. As ferocious in the studio as they are onstage, Sleigh Bells smash together hip-hop samples, techno beats, thrash metal riffs, and shout-along hooks to create a sound that's both fearsomely aggressive and undeniably catchy, with the charismatic Krauss combining the snarl of punk with the sugar-coated delivery of a dance floor diva. Cute and chaotic all at once, this Sleigh Bells collection is a blast of noisy indie bliss.
