Maroon 5 headlined the fifth Sounds of Hope for Children concert, held March 06 at the “Tangerine Lounge,” a one-night-only concert venue at the Del Mar Fairgrounds. Front man Adam Levine and his bandmates belted out their infectious pop tunes for the cause — proceeds benefited Rady Children’s Hospital and Health Center’s Neonatal Intensive Care Unit. Attendees participated in a live auction, cocktail hour, dinner and, of course, the concert.
