Ever the shape-shifter, Gwen Stefani's transformed before our very eyes over the past decades — from No Doubt ska-rock goddess to "Hollaback Girl" solo pop superstar to a "Luxurious" L.A.M.B. fashion darling to her most recent stint as a guiding light as a mentor on The Voice.

But throughout all her transformations, one thing's remained the same: Gwen Stefani gives good show.

Time and time again, all the way back to the early days with No Doubt to promoting her most recent solo studio album, This Is What the Truth Feels Like, the superstar performer's proved she's got the unique pipes to carry a song, whether accompanied by her longtime band or standing solo. And so, we've turned the spotlight on the "What You Waiting For" pop icon in our latest Best Live Vocals compilation series.
