John Legend and the Roots have kindly given Rolling Stone this exclusive acoustic performance of Eugene McDaniel's soulful anti-war track "Compared to What," which appears in electric form on their new covers album, Wake Up!, which hits stores today. The track was recorded in the Roots' NYC rehearsal studio. "John Legend is modern R&B's classiest male singer, bringing old-fashioned suavity to hip-hop soul; the Roots are the world's most versatile (and maybe best) band," Jody Rosen writes in his Rolling Stone review of Wake Up! , which earns four stars. "Together, they have made a brilliantly conceived and executed album, reviving music from the Nixon-era heyday of politically engaged R&B."
