Muse are longtime Coachella veterans, with a lot of hours logged on the main stage, and this year they returned with favorites like the obsessive "Madness" and bouncing rock of "Time Is Running Out." But fans of the British band have experienced no bigger surprise than the cover song that singer Matthew Bellamy said was dedicated to "a great singer who died 20 years ago." With that, Muse dove into an entirely faithful take on Nirvana's "Lithium" that had the crowd shouting along from the opening lyrics. Just days earlier, Nirvana were inducted into the Rock and Roll Hall of Fame at a ceremony in Brooklyn. For a moment, the crowd must have felt like they were there.
