The sold-out audience talked back to sisters Johanna and Klara Soderberg in Swedish accents, which caused the siblings, better known collectively as First Aid Kit, to blush and laugh. The duo, who are in their early 20s, stepped onto the stage of the Crescent Ballroom to a crowd that knew them better than they knew themselves.
This created such an ease between performer and listener that no calls for audience participation were necessary when the band began with "Shattered and Hollow," a song from their upcoming album Stay Gold. The Soderberg sisters were almost thrown off from their two-part harmony to accommodate the singing from the members of the audience. The crowd even kept rhythm with their hand claps during "King of the World" from their previous album The Lion's Roar.
