”I like to call it rock & soul,” says Alicia Keys of ”Another Way to Die,” the theme song for the next James Bond movie, Quantum of Solace. Written and produced by Jack White and featuring Stax’s legendary Memphis Horns, the song was recorded at the White Stripes frontman’s Nashville studio in June. ”It’s kind of like a roller coaster because it gets really big and loud, then it gets pulled in and soft,” she says. ”There’s also a fly part where Jack’s soloing on the guitar and I’m scatting. It’s a dope mixture of our styles.”
