Vitalogy is the third studio album by the American alternative rock band Pearl Jam, released on November 22, 1994 through Epic Records. Pearl Jam wrote and recorded Vitalogy while touring behind its previous album Vs. (1993). The music on the record was more diverse than previous releases, and consists of aggressive rock songs, ballads, and several experimental tracks.
Vitalogy was packaged in a booklet that replicated material from a 1920s medical book. The album was first released on vinyl record, followed by a release in other formats two weeks later on December 6, 1994. Upon its CD release, Vitalogy became the second-fastest-selling album in history, behind only Vs. The album has been certified five times platinum by the RIAA in the United States.
