On episode 25 of Epic Albums, Mike and Greg tackle one of the powerhouse albums of hard rock: Led Zeppelin's fourth. Whether you call it Zeppelin 4, Runes, or Untitled, it's such an undeniable classic that some people are legitimately tired of hearing about it. The guys cover that topic and review the songs When the Levee Breaks, Four Sticks, Stairway to Heaven, Rock and Roll, Black Dog, Battle of Evermore and Going to California.
