Joshua Radin

Singer/songwriter Joshua Radin has slowly but surely made a name for himself, thanks to a little help from Zach Braff. Braff used his clout to put his longtime friend’s song, “Winter,” on his popular-ish dramedy “Scrubs,” which provided enough of a profile boost to get Radin a recording contract. Since then, Radin’s Elliott Smith-without-the-demons songs have been regularly featured on “Grey’s Anatomy.” Radin shares tonight’s 7:30 p.m. bill at the Pabst Theater with singer-songwriter Alexa Wilkinson and, interestingly, Vanessa Carlton, the piano-pop songstress who five years ago seemed poised for a promising career, thanks to her dramatic pause mega-hit “A Thousand Miles.” For unclear reasons, her label pulled the promotional rug out from under her, and she’s been largely below the radar ever since.
