24 hours before Music’s Biggest Night, Gwen Stefani threw a pre-Grammy bash at Los Angeles’ Orpheum Theatre, where she performed her first full solo concert in almost eight years. At the Orpheum show, in addition to tracks culled from her solo LPs Love.Angel.Music.Baby and The Sweet Escape, Stefani sang her two new singles “Spark the Fire” and “Baby Don’t Lie,” her Calvin Harris collaboration “Together” and, for the first time, a new ballad called “Start a War,” co-written by Sia.
