With five number one singles, 14 Top 40 hits, and four number one albums, the Eagles were among the most successful recording artists of the 1970s.
At the end of the 20th century, two of those albums -- Their Greatest Hits (1971-1975) and Hotel California -- ranked among the ten best-selling albums ever, and the popularity of 2007's Long Road Out of Eden proved the Eagles' staying power in the new millennium. Though most of its members came from outside California, the group was closely identified with a country- and folk-tinged sound that initially found favor in Los Angeles during the late '60s, as championed by such bands as the Flying Burrito Brothers and Poco (both of which contributed members to the Eagles). But the band also drew upon traditional rock & roll styles and, in its later work, helped define the broadly popular rock sound that became known as classic rock. As a result, the Eagles achieved a perennial appeal among generations of music fans who continued to buy their records many years after they had split up, which helped inspire the first of the Eagles' reunions in the mid-'90s.
The Eagles' extensive touring kept them out of the studio, and with no immediate plans for a new album; they agreed to release a compilation, Their Greatest Hits (1971-1975), in February 1976. The album's success proved to be surprisingly meteoric. It topped the charts and became a phenomenal success, eventually selling upwards of 25,000,000 copies and dueling with Michael Jackson's Thriller for the title of the best-selling album of all time in the U.S. It took the Eagles 18 months to follow One of These Nights with their fifth album, Hotel California. Released in December 1976, the record was certified platinum in one week, hit number one in January 1977, and eventually sold over 10,000,000 copies. The singles "New Kid in Town" and "Hotel California" hit number one, and "Life in the Fast Lane" made the Top 20. Meanwhile, "Hotel California" won the 1977 Grammy for Record of the Year and was nominated for Song of the Year; the album itself was nominated for Album of the Year and for Best Pop Vocal Performance by a Duo, Group, or Chorus.
