Boardwalk Empire would be nothing without its roaring soundtrack. Jazz was on the up and up during the show's 1920s setting, and the music itself has become a character that's almost as important as Nucky himself. The first volume of the show's tunes won a Grammy for best compilation soundtrack for visual media, and the second volume will be out next week. For those who can't wait, Boardwalk Empire Volume 2 is streaming exclusively via Billboard (or below) until its Sept. 3 release. It's easy to forget how many great songs came out of the 1920s, and with artists like Patti Smith, Liza Minelli, Neko Case, and Rufus Wainwright belting out their own renditions, it's the bee's knees. Consider this soundtrack best enjoyed whilst sipping on the finest hooch and cutting a rug with a few swell shebas and sheiks.
