Led Zeppelin released their second studio album, aptly titled Led Zeppelin II, produced by the band's guitarist, Jimmy Page.
The album was the rocker's first #1 hit in both the U.S. and U.K., and featured the future Zeppelin classic "Whole Lotta Love," which peaked at #4 on the Billboard Hot 100 and was a top 10 hit in several other countries around the world.
