The Eagles' Classic 'Hotel California' Album Turns 40 Today

— -- Today marks the 40th anniversary of the release of The Eagles' landmark album, "Hotel California."

The band's most successful studio effort, "Hotel California" has sold more than 16 million copies in the U.S. alone. The album spent eight nonconsecutive weeks atop the Billboard 200 in 1977 and yielded two No. 1 hits, "New Kid in Town" and the title track, which is widely considered to be one of the greatest rock songs of all time.

Ex-Eagles guitarist Don Felder, who wrote the music to "Hotel California," told ABC News he feels the band was at its creative peak when they recorded the song and the album.

"I thought it was an unbelievably magical combination of five guys -- writing, musicianship, the ability in the studio from the experience we had all had in the years we had spent making records," Felder said.

"Hotel California," The Eagles' fifth studio release, was the first to feature guitarist Joe Walsh, who replaced founding member Bernie Leadon. Walsh's blistering work added a harder edge to the band's sound, exemplified by his contributions to the title track and "Life in the Fast Lane," a No. 11 hit for the group.

The song "Hotel California" serves as both the launching point and thematic centerpiece of the album, which is a loose-concept record about life in the decadent music business in southern California during the '70s.

As Felder explained, "Once we had the foundation of the concept of 'Hotel California,' all these other songs started coming out. Like, when you first get to LA and you get in the music business and you have your first hit, you're the 'New Kid in Town.' And then, once you start flying around in limos and Learjets and living that lifestyle, it becomes 'Life in the Fast Lane.'"
