After celebrating their recent induction into the Rock and Roll Hall of Fame with a three-song performance at the ceremony and a three-hour, career-spanning show in Cleveland, it appears Green Day are ready to build upon that legacy. Producer Rob Cavallo -- who has worked on the trio’s last nine albums – revealed that frontman Billie Joe Armstrong has been working on new music.

“I recently heard five new songs that Billie has written and demoed,” Cavallo told Kerrang. “Let me tell you, they were just fantastic. He is absolutely at the top of his game. Fans can be sure that when they do return, the music will be amazing.”

Armstrong hinted at the band’s plans for 2015 in a Facebook post last year. Green Day dropped their triple-LP series, Uno!, Dos! and Tre! back in 2012.

Armstrong, Mike Dirnt and Tre Cool were inducted into the Rock and Roll Hall of Fame last Saturday (April 18), along with Lou Reed, Joan Jett and the Blackhearts and more. After Fall Out Boy presented Green Day with the honor, Armstrong said he was “kind of lost for words” during the band's acceptance speech.

“The gratitude I feel right now is overwhelming,” he said. “I love rock and roll and I’m going to for the rest of my life.”
