Directly following Ed Sheeran and ELO at the Grammys, Adam Levine and Gwen Stefani performed their duet "My Heart Is Open" from Maroon 5's 2014 album, V. While Stefani brought a heavy dose of emotiveness to her half of the duet, Levine kept it simple for the ballad. Following Ariana Grande's massive drama for "Just a Little Bit of Your Heart," Levine and Stefani's slow song felt a little lackluster.
As Stefani prepares her third solo release, slated to come out this year, Levine and his Maroon 5 bandmates are still riding high on the success of V (though the album was not nominated for any awards this year). Maroon 5 has won three Grammy Awards, including a 2005 Best New Artist win over Kanye West. All of Stefani's Grammy wins came before her first solo album release and included two with No Doubt and one for her collaboration with Eve on "Let Me Blow Ya Mind."
Levine has been a staple of the Grammy performance roster in recent years. His last appearance, in 2013, included duets with Alicia Keys on Maroon 5's "Daylight" and Keys' "Girl on Fire." The year prior, he joined Foster the People and the Beach Boys for a tribute to the latter. Stefani's last appearance as a Grammy performer was in 2005 as part of medley with Maroon 5, Black Eyed Peas, Los Lonely Booys and Franz Ferdinand where she sang "Rich Girl" with Eve.
Stefani debuted her new song "Start a War" at a pre-Grammy concert Saturday night; her first solo concert in nearly eight years. Keeping with Stefani tradition, the singer chose not to perform any No Doubt tracks live without her band mates, instead focusing completely on her solo work.
Stefani's time as a fellow coach with Levine on The Voice was short-lived, as Christina Aguilera will be returning to the chair when the show's eighth season premieres on February 23rd. The "Baby Don't Lie" singer has also collaborated with fellow coach Pharrell Williams recently on the song "Shine" for the film Paddington as well as her latest single for her forthcoming album "Spark the Fire."
