Last night, Gwen Stefani performed her first full solo concert since 2009 at Los Angeles’ Orpheum Theatre. She ran through tracks from her first two solo albums, sang her new singles “Baby Don’t Lie” and “Spark The Fire,” and performed her Calvin Harris collaboration “Together.” She also debuted a new song, a ballad called “Start A War” that was co-written by Sia, and will presumably appear on her forthcoming third solo album. Watch video of her performing that track below.
