David Byrne talks about what makes his latest album and tour, titled "Who Is The Sky?," different from his previous work, "American Utopia." One thing that is very different is the use of video footage of Trump's immigration raids, which Byrne shows on video screens while performing a Talking Heads classic, "Life During Wartime." Watch as the Rock & Roll Hall of Famer explains why he delves into politics on this tour, and stick around for a performance of a song from "Who Is The Sky?" #Colbert #
