The Rock and Roll Hall of Fame unveiled its class of inductees for 2015 on Tuesday, and heavy metal fans immediately noticed that iconic bands like Iron Maiden, Deep Purple, and Judas Priest have yet again been left off of the list. Critics are calling the snubs an ultimate sign of disrespect, and several rockers are already voicing their lack of trust in the Hall of Fame’s voting body.

Exodus lead singer Steve “Zetro” Souza has long since given up any hope of seeing his band in the Rock and Roll Hall of Fame, even though their music has been the soundtrack for moshpits for nearly thirty years and their latest album, “Blood In, Blood Out,” reached the Billboard’s Top 40 charts. However, he told the Daily News on Tuesday that the lack of recognition for other top bands in his genre is starting to make him angry.

“Iron Maiden goes to anywhere in the world and they play in front of 50,000 people by themselves and you telling me they don’t f— belong in there? In our type of music, we don’t expect kudos. But it’s hard not to be disappointed by the voting.”

Souza visited the Rock and Roll Hall of Fame and Museum in Cleveland last year for the first time, and was shocked by some of the artists that were honored there.

“There was a Bruno Mars suit there, but he didn’t put in the time. There’s a Katy Perry dress there, but she hasn’t put in the time.”

Radio host Eddie Trunk has also lost respect for the Hall of Fame’s voting body following Tuesday’s unveiling of the 2015 inductees, and stated that it is ridiculous that seminal rock band Deep Purple still hasn’t made the cut even though they inspired a large number of the bands that have.

“How can you have a Hall of Fame where it takes Kiss, Rush and Alice Cooper twenty years to get in, but Green Day and Guns n’ Roses go in on first ballot?”

“This is a symptom of the disrespect across the board toward hard rock and heavy metal. The Grammys haven’t gotten any better since they gave Jethro Tull a Grammy instead of Metallica.”

This disrespect for hard rockers was made even more evident when late Slayer guitarist Jeff Hanneman was omitted from this year’s “In Memoriam” segment at the Grammys. Souza said that, while metal acts like Black Sabbath and Metallica finally getting their own displays in the Rock and Roll Hall of Fame and Museum is a decent start, he doesn’t expect the disrespect for hard rock to change any time soon.

“For those of us who have been doing this for thirty years, we don’t care about or expect anything from the establishment.”
