During her first live show in almost eight years, Gwen Stefani previewed a brand new track last night, as part of her pre-Grammy party in LA.

Start A War, which appeared in an exhaustive set spanning Stefani’s long-term solo career, follows the singer’s multiple comeback singles, Baby Don’t Lie and the Pharrell-produced Spark The Fire, and hears co-writing credits from the multi-Grammy Award-nominated Sia.

Check out the fan recording of Start A War below; Gwen Stefani is set to take to the Grammy Awards stage later this evening for a duet with Adam Levine (the song choice yet to be confirmed).
