For their sixth album, the Black Keys landed at the legendary Alabama studio Muscle Shoals and crafted their mainstream breakthrough, with elements of glam, garage-rock and the blues throughout the LP. “Tighten Up” was the most popular song, but Brothers boasts an abundance of quality tunes. From the pulsating drive of “Howlin’ for You” and the soulful lament of “Next Girl” to the down-home romance of “Everlasting Light” and sleazy swing of “Ten Cent Pistol,” Brothers creates an engrossing world. The album resonated with listeners and critics alike, becoming the Black Keys' first platinum-selling record and earning the duo three Grammy Awards.
