Rufus with Sly Stone

What in the living what, now? Sly Stone? The last we'd heard of the legendary pioneer of soul-funk, who croaked out such delicious hits as "If You Want Me to Stay" and "Everybody Is a Star," was that he was living in a camper van in L.A. But here he is, playing with ’70s funk trailblazers Rufus. This could be…otherworldly.
