Mothership is a compilation album featuring songs from Led Zeppelin, LZII, LZIII, LZIV, Houses of the Holy, Physical Graffiti, Presence, and In Through The Out Door. There are two deluxe editions that come with a DVD featuring several live performances.
Pitchfork reviewed the collection, saying:
Mothership offers no bonus content or previously unreleased material. It serves, mainly, as an introduction for those (presumably out of classic rock radio range) still unfamiliar with the band. Longtime fans will find little of use here, although anyone who spends a couple hours with Mothership will find themselves duly reminded that Led Zeppelin are quite possibly the finest rock band of all time.
