Rare tapes containing rough mixes and unheard material recorded by Led Zeppelin for Physical Graffiti have resurfaced at auction.
Heritage Auctions has listed for sale two reel to reel tapes previously owned by Led Zeppelin engineer Ron Nevison in its latest auction which ends on December 6.
The tapes contain rough mixes of Led Zeppelin recording songs such as “Kashmir”, “Custard Pie” and “Ten Years Gone”.
Nevison attempted to sell the tapes at auction in March 2014, but the auction listings for the tapes were taken down before sale. Led Zeppelin’s record label also issued copyright strikes to remove samples of the audio that had been provided by RR Auction.
Receipts included in the new auction show Nevison privately sold the tapes to Mark Haverkos for $10,000 on October 16, 2014.
Information on the receipts suggest the 2014 purchaser was veterinarian Dr. Mark Paul Haverkos who died on February 2, 2025.
The first tape is believed to be the same rough mix which was used for the bootleg release Oh My God which emerged around 1997, albeit with worse quality than these tapes.
Here are the tracklists for the two tapes:
Tape one
- Trampled Underfoot (5:40)
- Driving To Kashmir (8:50)
- Custard Pie (4:20)
- In The Light (Everyone Makes It Thru) (7:18)
- Swan Song – Part 1 (1:20)
- Swan Song – Part 2 (3:39)
Tape two
- In My Time Of Dying (10:50)
- Sick Again (4:39)
- Désiré (The Wanton Song) (4:10)
- Ten Years Gone (6:55)




I sure hope I get to hear or I can buy these songs some day.A few years back Robert Plant said that they have many unreleased songs that will make the hair on the back of your neck rise!
