The two members of Americana duo The Civil Wars are now engaged in a war with each other that has, ironically, left the band divided against itself. The group has canceled all of its upcoming dates, saying that “due to internal discord and irreconcilable differences of ambition,” it’s “unable to continue as a touring entity at this time.” While the band promises new material in 2013, a lot of fans are wondering if this is the end of an act that only just released its very successful debut, Barton Hollow, last year.
