Upon its CD release, Vitalogy became the second-fastest selling album in history, only behind the band's previous release Vs., selling 877,000 copies in its first week. The album has been certified five times platinum by the RIAA in the United States. This is Pearl Jam's last album to feature drummer Dave Abbruzzese.
