Justin Bieber surprises crowd with impromptu MacArthur Park concert

Justin Bieber performed an impromptu mini-concert Tuesday at MacArthur Park in Los Angeles, singing several songs for a surprised crowd. The free show quickly went viral on social media. Dressed casually in a white t-shirt and shorts, Bieber was backed by a small band playing acoustic and electronic instruments. The set list included "Speed Demon," "All I Can Take," and "Yukon." Los Angeles County District Attorney Nathan Hochman praised the performance as evidence of progress reclaiming the park from drug dealers, while First Assistant U.S. Attorney Bill Essayli called it a sign of improvement after criminals were removed from the area.
