As if Gotye’s “Somebody That I Used to Know” wasn’t popular enough in 2012, the Canadian act Walk Off the Earth put their own creative spin on it, releasing a low-budget video with five people playing one guitar. Their cover, which has received more than 156 million hits on YouTube, catapulted them from obscurity. The pop-rock band has gone on to cover many Top 40 favorites accompanied by innovative videos. Last year they released R.E.V.O., an LP of mostly originals that featured the minor hit “Red Hands.”
