Nick Jonas and Demi Lovato took a risk in going relatively straightforward and simple for the Brooklyn stop of their 42-show Future Now tour: no knife-sharp choreography, no flocks of strapping dancers, no impractical props cluttering the stage and only one wardrobe change for Lovato.

Instead, their voices were front and center on the Barclays Center stage before a nearly full house of tweens, teens, parents and twentysomethings alike, with Jonas taking the audience through most of his No. 2 charting album Last Year Was Complicated and hits from his self-titled debut, while Lovato highlighted dance-pop tracks, ballads and fan-favorites alike.
