Josh Groban at Hollywood Bowl

For years the Hollywood Bowl has been the most reliable source for L.A. Fourth festivities, and here it heads into Independence Day with pop-classical singer and pianist Josh Groban, who will fill the Bowl with his own material. The day also features the L.A. Philharmonic performing a set of patriotic music accompanied by an always-dazzling fireworks set. 2301 N. Highland Ave., L.A. 7:30 p.m. Thu. Prices vary. https://www.hollywoodbowl.com.
