In the ongoing debate of rock supremacy, we pose the question: Which Led Zeppelin masterpiece reigns supreme—IV or Physical Graffiti? This is the exciting matchup featured this week in Loudwire Nights’ Chuck’s Fight Club.

Recognized as one of the most influential bands in the history of hard rock, Led Zeppelin, consisting of the legendary talents Robert Plant, Jimmy Page, John Paul Jones, and John Bonham, established their dominance in the music scene of the ’70s with a series of groundbreaking albums. However, our focus today is on two specific albums that shaped their legacy, and we invite you to share your opinion on which one stands out as the superior record.

The band’s untitled album from 1971, commonly referred to as Led Zeppelin IV due to its place in the band’s discography, boasts an impressive lineup of timeless tracks. The first side alone features iconic songs such as “Black Dog,” “Rock and Roll,” “The Battle of Evermore,” and the legendary “Stairway to Heaven.” Additional classics like “Misty Mountain Hop,” “Going to California,” and “When the Levee Breaks” further enrich this album, which soared to No. 2 on the Billboard 200 and achieved an astounding 24 times platinum certification in the United States.

Having topped the charts as well, this iconic album has been certified 16 times platinum in the U.S., solidifying its place in rock history.
