Katy Perry’s ‘Roar’ Gets Rocked Out by Wolf Alice [Video]

Wolf Alice turns up the rock volume with their cover of Katy Perry's song 'Roar.' The subtle beginning may throw viewers off at first listen; the singer's soulful yet soft-spoken voice doesn't scream rock and roll. But when the rocking rhythm section and jamming guitars kick in, the song delivers a rollicking energy that demands attention.

A relatively new band formed in 2010, Wolf Alice hails from North London. Their music is described as grunge and alternative rock, giving them a unique sound that, while keeping a softer side to their music, also has the ability to produce a heavy beat with strong guitar melodies.

This cover of 'Roar' kicks it up a notch and really delivers some explosive sound, transforming Katy Perry's power pop song into a track worthy of rocking even when people are looking.
