Joshua Radin has the kind of voice that invites you to lean in and beg him to tell you more. The American troubadour murmurs his lyrics, matching his gently weathered croon to the muted strum of his acoustic guitar. He started writing and performing his songs in the mid '00s, and broke through when his Nick Drake-inflected ballads—sun-speckled and windswept vignettes about vulnerable characters working hard to connect—landed on the Scrubs soundtrack. He's honed his craft and made precise tweaks to his sound since then, but he remains true to the rustic intimacy at the heart of his songs.
