This is the year of extravagant “revenge weddings,” and members of the nupital party are paying the price in money, time, and emotional energy. Chicano Batman, often known as “LA’s house band,” will perform at the Hollywood Bowl this weekend for the first time. You can head to El Segundo to hear a 13-piece big band while dancing the night away at the sixth annual Summer Swing Nights, which runs August 4, 5, and 6.
