Lenny Kravitz performed “When Doves Cry” and “The Cross” at the Rock and Roll Hall of Fame Induction ceremony on Friday in honor of Prince, who died last year at the age of 57. Kravitz was assisted by Hezekiah Walker and the Love Fellowship Choir, who imbued the songs with uncontainable fervor. Kravitz opened with a slow-burn “When Doves Cry,” which he re-worked as pointy gospel-funk. His guitarist sprayed a series of gnarled, pointy riffs, and the organ player held long-sustained notes. Kravitz, wearing his usual Aviator sunglasses and black leather pants, kept time with a tambourine. He strapped on his guitar for “The Cross,” a rumination on human suffering and the afterlife from 1987’s Sign o’ the Times. The song started with languid keyboards, but the calm didn’t last for long: soon Kravitz was playing full volume and the drummer beat out a merciless stomp. Still, both their efforts paled next to the power of the choir, which helped “The Cross” land with the full impact of gospel.
