Hollywood stars Julia Roberts and Zendaya bookended Saturday’s inductions into the Rock & Roll Hall of Fame, giving a little stardust to an eclectic lineup that included pop icon Cher, heavy metal’s Ozzy Osbourne, hip-hop soul queen Mary J.

Before there was the Clash, Nirvana or Rage Against the Machine there was the MC5.

Among those paying tribute to MC5 guitarist Wayne Kramer are prison reform advocates.

Wayne Kramer, co-founder of the protopunk Detroit band the MC5 that thrashed out such hardcore anthems as “Kick Out the Jams” and influenced everyone from the Clash to Rage Against the Machine, has died at age 75.
