Los Angeles, 1949. Ruthless, Brooklyn-born mob king Mickey Cohen (Sean Penn) runs the show in this town, reaping the ill-gotten gains from the drugs, the guns, the prostitutes and—if he has his way—every wire bet placed west of Chicago. And he does it all with the protection of not only his own paid goons, but also the police and the politicians who are under his control. It’s enough to intimidate even the bravest, street-hardened cop…except, perhaps, for the small, secret crew of LAPD outsiders led by Sgt. John O’Mara (Josh Brolin) and Jerry Wooters (Ryan Gosling), who come together to try to tear Cohen’s world apart.

This is an amazing compilation of the music and songs featured in the film Gangster Squad. Many are swing, pop and famous songs from the film story's era, from the 1940s and 50s. Songs by big names and legends like Johnny Mercer, Hoagy Carmichael and Peggy Lee are included, as well as contributions from lesser-known names like Pee Wee King. The very modern St. Vincent has delivered her take on the standard "Early Autumn," that has previously been performed by folks like Woody Herman (who co-wrote it), Ella Fitzgerald, Mel Torme and more.
