“Immortal,” the new Michael Jackson-themed Cirque du Soleil show touring North America may sound grandiose but the self-proclaimed “King of Pop” was undoubtedly a larger-than-life character. While immortality was out of Jackson’s reach, the singer’s family are doing their best to keep his memory alive with musical extravaganzas. Two “Michael Jackson Tribute Live” concerts will take place Dec. 13 and 14 at Yoyogi National Stadium in Tokyo.
