Algiers — a band of Atlanta natives based in London — released a powerful self-titled debut album this summer. The music has been described as “dystopian soul,” and I can see why. Vocalist Franklin James Fisher hollers with the passion and style of a gospel or soul singer, but the musical arrangements surrounding his voice are a dark, almost art-rock mix of many varied elements. The band played Oct. 6 at the Empty Bottle, with a live sound that was pretty close to the studio recordings. At two points during the show, Fisher stepped down from the stage and sang amid the audience. He got down on his knees, almost seeming to plead as his sang his passionate, socially conscious lyrics. “You say your history’s over/All my blood’s in vain,” he implored in the song “Blood.”
