Physical Graffiti is Zeppelin unleashed. Fifteen tracks, four sides, no rules. From the sleaze of “Trampled Under Foot” to the desert sprawl of “Kashmir”, from their shortest son ever "(“Bron-Yr-Aur”) to their longest (“In My Time of Dying”), it’s the full Zeppelin spectrum.

Along the way: Bonham’s cough left in the mix, a jam with the Stones’ Ian Stewart (“Boogie With Stu”), a royalty check mailed to Ritchie Valens’ mom, and even a passing airplane on “Black Country Woman.” It’s raw, indulgent, and bigger than any band had dared.

And on our podcast, we’ve got it all: Best Track, MVP, Kate’s Rate, Matthew’s Headphone Moment, Ryan’s A&R Guy take and the full McGuigan debate over which side of Physical Graffiti really wins.
