Hot on the heels of their stellar main stage performance at Knotfest in San Bernardino, CA, last night, this week’s edition of Massive Metal Monday is dedicated to metal stalwarts Clutch. I’ll be telling you more about Clutch’s performance and the entire Knotfest festival in the days to come. But, in the meantime, check out the band’s latest single. From their phenomenal eleventh album, Psychic Warfare, which was released earlier this year, this is “X-Ray Visions.”

When I was growing up in rural Indiana in the early ’80s, there was very limited access to heavy music. These were the days before MTV blew up with the whole hair metal, Headbangers Ball phenomenon. But on Sunday nights, there was a two-hour radio show that came from WOXY, just across the state line in Oxford, Ohio (home of Miami University of Ohio). It was called Massive Metal for the Masses, and I would wait all week for it to air. It was through this show that I was introduced to bands like Venom, Bathory, WASP, Michael Schenker Group, Slayer, and countless others. This Monday weekly column is my tip of the hat to that show. I call it Massive Metal Monday. Every week, I pay tribute to defining moments by the artists that laid the groundwork for heavy metal to become the worldwide cultural bond for all of us metal heads.
