Firefighters quickly knocked down a "stubborn'' brush fire across the street from the Hollywood Bowl and no injuries or structure damage was reported, authorities said. The fire was reported at around 11 p.m. Saturday on Highland Avenue near the Hollywood (101) Freeway as concertgoers were leaving a "Sound of Music" singalong at the Bowl. Several people posted video on social media showing how a small fire quickly exploded with flames shooting in the air dramatically before being extinguished. Another observer noted the fire "came out of nowhere'' and "literally just combusted." At one point the Los Angeles Fire Department asked the California Highway Patrol to Patrol shut down one lane of freeway traffic while they battled the flames.
