The Decemberists brought May to a magnificent start on Saturday night when they returned to College Street Music Hall for the fourth show of their 2024 A Peaceable Kingdom North American tour. Fans filled the room from floor to balcony, up the stairs and to the edges of the stage barrier, to bask in the multicolored hues of the lights and lofty sounds of some of their favorites, mixed in with new material from the band’s aptly titled upcoming album As It Ever Was, So It Will Be Again.
