Unlike most of their classic rock contemporaries, Led Zeppelin seem to have had an easier time keeping their studio demos out of the hands of bootleggers. Live material? That’s easy. There are live Led Zeppelin concerts all over the Internet, but previously unreleased studio material is quite a bit harder to come by. Here are six Led Zeppelin recordings that you probably have never heard before. (Plenty of Led Zeppelin rarities here, too)

“Jennings Farm Blues” is basically an amped-up version of “Bron-Y-Aur Stomp,” from Led Zeppelin III. Bonzo’s amazing here, as always, but especially amazing, if you ask me.
 

 
“Sugar Mama” came from a 1969 session. This is a cover of the Sonny Boy WIlliamson song and has nothing to do with a ditty of the same title by Tila Tequila…
 

 
A very different take on “The Rover,” a key track from 1975’s Physical Graffiti
 

 
“In the Morning” is an earlier version of “In the Light.”
 

 
“Take Me Home,” another out-take from the sprawling Physical Graffiti sessions.
 

 
And finally, here’s “Swan Song.” an epic ten-minute long demo of what would later become, “Midnight Moonlight,” by The Firm, Page’s post-Zep outing with Paul Rodgers of Bad Company.
