As her team members competed for their place in next week's finals, Stefani took the stage in a multicolored, bejeweled jacket with tassles and thigh-high boots to rock out to her new single -- which insists "I'm still the original, original me" -- in front of giant video screens showing old video clips and backup dancers in masks and the "Just a Girl" look.
Stefani opened up about her new music to The Zane Lowe Show on Apple Music, sharing that she wrote several songs during the coronavirus pandemic lockdown.
"I just was like, 'I don't even care if nobody hears this, I got to write some songs,'" she said. "So it was almost like I didn't have anything to say. I didn't think until I started writing."
As a solo artist, Stefani has released 2004's Love. Angel. Music. Baby, 2006's The Sweet Escape, and 2016 This Is What the Truth Feels Like, in addition to her 2017 Christmas album, You Make It Feel Like Christmas.
"I know what kind of music I want to make. And I want to make music that makes people feel happy," she shares. "There's just nothing else that I do in my life, and I have done so many things, that makes me feel ignited the way a new song makes me feel."
In her statement about the release of the new song, Stefani made it clear that the throwback feeling of the track was intentional.
"The idea was to write a song that had a bit of a nostalgic feeling to it, so I think musically it reminds you of back in the day, going back to where I started musically which was with ska and reggae," she says. "I'm still the same me but here's something a little bit new in case you feel like hearing a little bit more of me."
The Voice airs Monday and Tuesdays at 8pm PT/ET on NBC.
