Bobby Darin shifted musical styles throughout his career with a kind of restless abruptness, by turns a teen idol, big-band jazz singer, rock & roll singer, Vegas crooner, pop singer, and folk-rocker, a maverick in the public eye if there ever was one. He was, in a sense, the bridge between the Frank Sinatra generation and the generation that rushed in with the Beatles and Bob Dylan. This set collects some of his early sides, including "Dream Lover" and "Splish Splash," both of which show Darin as a better-than-average teen idol-styled singer, and his signature song, "Mack the Knife," a tune from Brecht-Weill's Threepenny Opera musical, hit the top of the pop charts in 1959 and showed Darin moving away from his teen roots toward a more sophisticated jazz approach. There's more to the Bobby Darin story than these early tracks, of course, but his legacy began with the sides collected here.
