What’s the difference between Heavy Metal and 1970s Rock & Roll? It isn’t the 1970s anymore. Or that is mostly my take, unless you are talking about Symphonic or Power Metal, or Melodeath etc.
Tremonti is 1970s Rock & Roll produced today, so it is Heavy Metal. Are we surprised that they had to go to Austria to find a record label? Suits running the American Music Industry are completely insane.
This is “As The Silence Becomes Me” by Tremonti from the 2018 album A Dying Machine. Some of the songs on that album are harder than this one, but this is still hard rock. (YouTube. Browser Privacy Extensions. “Unavailable.” Use link above.)
