Snoop Dogg, now known as Snoop Lion, is making a roaring comeback. The rapper did a guest performance and DJ set at the Box on Friday night to celebrate the release of his new reggae album, “Reincarnated.” Snoop and his crew hung out upstairs watching regular house acts, such as a “Wizard of Oz”-themed break-dancing routine, before taking the stage. Last week, Snoop previewed his documentary, also called “Reincarnated,” at Bowery Hotel.
