A set of two “acetate” CD/Reference Discs for the 2007 Led Zeppelin two CD compilation Mothership.  Released November 12, 2007, Mothership was the first Zeppelin greatest hits set and was a worldwide best seller.   This is a two-CD set of the mastered, EQ’d album made at Alchemy Studios in Soho, London for the band, management and record label to approve.  We acquired this directly from someone who worked closely with the band on the project.  The inserts are dated August 31, 2007; and the CD’s are in perfect condition, as are the inserts. The covers the jewel boxes have some scuffing and one has a small crack.  One of perhaps five or six sets made.
