SXSW is crazy. How crazy? So crazy that on the morning of the last day, we found ourselves in some eccentric millionaire’s South Austin mansion, tucked away at the very top of a tower, while the lovely Nicole Atkins crooned this homage to Amy Winehouse’s “Rehab.” Crazier than that? Even though she, like everyone else in the city that morning, was hungover and exhausted, Atkins pulled it off on the first take. Just in time, as seconds after wrapping, a band started playing below. For more of Jersey local Atkins’s Springsteen-approved music, get your mitts on her new album, Slow Phaser.
