The Soul Music of Leon Bridges

The Texas singer Leon Bridges emerged, in 2015, as a convincing throwback, with everything from the shoes on his feet to the croon on his lips paying homage to a faded era of classic soul. In his more recent work, including last year’s down-tempo LP, “Gold-Diggers Sound,” the singer effectively reset his time machine to the present, covering a breadth of soul music in the process. On Aug. 18, Bridges headlines at Forest Hills Stadium, with an opening set from the Swedish electro-pop band Little Dragon.
