In this week's episode, the guys explore the fourth Led Zeppelin album, track by track. Though it is often cited as a precursor to hard rock and heavy metal, Led Zeppelin's IV is a diverse album exploring the past and future of rock music, and it has influenced musicians for 50 years. Our independent record store of the week is Ft. Lauderdale, Florida's Radio Active Records. As always, we thank our sponsor Anchor.fm for their support.
