Much has been made about Carly Rae Jepsen's career resurgence, which came to a head last night when she performed two songs on Saturday Night Live. Naturally, she began the proceedings with her latest earworm "I Really Like You," but it was her second song that stunned. "All That" is a shimmering retro ballad that marks a whole new sound for the Canadian pop star. And if the woozy slow jam sounds familiar, that's because it was crafted by producer-du-jour Dev Hynes, who joined Jepsen on stage (and gave her all the cool cred ever in the process).

Watch Jepsen and Hynes be "All That" below.
