When NME listed electro-thrashers HeartsRevolution as one of the top 50 acts driving music forward in 2008, nothing could have been more of a surprise for the boy-girl duo; yet nothing could have been more deserved either. Already known across the indie circuit for their epitomic DIY entrepreneurship via their Hearts Challenger-branded lifestyle/ice cream trucks, which sell everything from domestic treats to merchandise from international artists and bands across major cities in the United States, HeartsRevolution has finally made an impression on the music world via their latest release, the Switchblade EP.

At 16 minutes too short, the 5-song compilation struts the best sounds the duo has recorded to date, sans their most popular track “C.Y.O.A.,” an acronym meaning Choose Your Own Adventure, the driving mantra of Hearts. By no means is HeartsRevolution new to the music scene, having released a track on the famed French record label Kitsune Maison’s sixth compilation; a split vinyl with fellow boy-girl twosome Crystal Castles, who serve as close accomplices and perhaps their biggest competition; and a couple of “C.Y.O.A.” vinyl releases. p>Switchblade, however, sees the band’s first full-fledged attempt at musical stardom, a feat that is everything but impossible. From the chainsaw-like rips of opener “Switchblade” to the schizophrenic yelps of “Wolves + Libertines,” Switchblade is the backbone of what would have been a stalwart full-length debut.
