Black Sabbath - "Into The Void"

Brian Slagel, the founder of Metal Blade Records, has spent a lifetime immersed in the sound and culture of heavy music. In his podcast, 100 Songs that Define Heavy Metal, he uses a personal list of essential tracks as a roadmap for a deeper conversation. Each episode focuses on a single, pivotal song from the realms of metal and hard rock, dissecting its creation, impact, and legacy. The real texture of this podcast comes from the guests who join Brian-a mix of the original architects behind these anthems and the later-generation artists who carried their influence forward. Listeners will hear firsthand stories from the studio, the tour bus, and the moments when a riff or a lyric permanently altered the landscape. It’s less a formal history lesson and more a series of passionate, insider dialogues about the recordings that built a genre’s foundation. You’ll come away from an episode not just with a greater appreciation for a specific track, but with a clearer understanding of how these one hundred songs connect to form a powerful, enduring whole. The conversations in this podcast naturally explore technique, cultural context, and the raw feeling that makes these compositions timeless.
