Biffy Clyro (2:25 PM Saturday, Coachella Stage): When we premiered Biffy Clyro’s driving cut “Modern Magic Formula,” Michael noted that the band’s stateside visibility was an ember to their massive glow in the UK. “How do you introduce a band on their sixth album, in their second decade of work, to an unfamiliar culture accustomed to early-adoption?” On Saturday, Biffy will take their incendiary music to the main stage and show why we should make them an American treasure. Be there when it happens.
