The Eagles are the most successful rock band in American history. Period. They are also the fourth best- selling music artist in the history of the country.

The Eagles embodied the 1970s like no other band and came to define and illustrate the allure of California. However, they have transcended both time and place. Their classic songs like "Take It Easy" and "Hotel California" are known worldwide and have inspired millions to dream of achieving a "Peaceful Easy Feeling" in the Golden State.

The band emerged from the late-sixties country-rock scene and wrote the genre's most successful and memorable songs. However, they attained their most tremendous success when they dared to transcend the country-rock mold and create a California rock style that is all their own.

It is hard to pinpoint the secret of the seemingly eternal appeal of the band. It is subtle yet unmistakable. But they combined the visceral and reassuring with a challenging and intellectual side. The result was a distinctive and irresistible sound.

Critics have maligned them for years. But we bet they all crank up "Take it Easy" when it comes on the radio. How can anyone resist those opening chords?
