Mint condition, perfect for any collector Led Zeppelin is the only album in their catalog to include the classic B-side "Hey Hey What Can I Do," as well as their unreleased version of Robert Johnson's "Travelling Riverside Blues" and a live medley of Page's "White Summer/Black Mountain Side." Most fans will find these three tracks essential, but will balk at the price, especially since all of Zeppelin's albums have been remastered since the original release of the box set.
