Led Zeppelin II, which followed in 1969, hit number one within two months of its release. The album, which was recorded during breaks in the band's American tour in support of their debut, is one of the first true heavy-metal recordings; it was largely made up of louder, harder covers of old blues songs. 1970's Led Zeppelin III saw the group beginning to grow away from their solid blues roots, with lyrics entering into the fantasy realm and not as sexually obsessed as their early works. 1971's Led Zeppelin IV was considered a must-own among rock fans of the era, containing the air-guitar classic "Stairway To Heaven." 1973's Houses of the Holy, like all of Led Zeppelin's albums, was a success with fans but was panned by critics. The album spawned funk-influenced metal songs such as "The Ocean," as well as folk-influenced songs such as "Over the Hills and Far Away" and the reggae song "D'Yer Mak'er." The group continued a grueling tour schedule throughout the '70s, consistently selling out arenas around the world. 1975's Physical Graffiti was the group's only studio-recorded double-album and contained such well-known songs as "Kashmir" and "Trampled Underfoot." While 1976's Presence was littered with throwaway tracks, it was 1979's In Through The Out Door that showed the band's versatility in the face of punk, disco and new wave. Songs such as the Latin-flavored "Fool In The Rain," the keyboard- driven ballad "All of My Love" and the traditional Zeppelin blues work-outs "I'm Gonna Crawl" and "In the Evening" showed that the band could remain true to its roots while adapting to the changing times. Unfortunately, hard-living drummer Bonham died in 1980 and the band immediately broke up. Page and Plant went on to highly successful solo careers, while birthday boy Jones has kept a relatively low profile. He produced the Butthole Surfers' Independent Worm Saloon and recorded The Sporting Life with avant-garde shrieker Diamanda Galas in 1994. In 1995, the group was inducted into the Rock and Roll Hall of Fame.
