Gene Simmons has hit out at the Rock & Roll Hall of Fame for not inducting Rage Against The Machine and Iron Maiden this year.The Hall announced its 2021 inductees earlier this week, with Jay-Z, Foo Fighters, Tina Turner, Todd Rundgren, The Go-Go’s and Carole King all entering this year.Among the artists who were nominated for induction this year were Rage Against The Machine and Iron Maiden, but their failure to make the Hall’s final cut for 2021 has irked KISS vocalist and bassist Simmons.“RR
