And what a voice it was.
Listen to some of her most impressive performances below.
Hello Adele
Grimmie spread holiday cheer last December by posting a cover of Adeles hit song Hello.
Together they sang a soft, soul-moving rendition of James Bays Let It Go.
They reunited again on a tour that kicked off at the end of May.
Canadian singer Mike Tompkins filmed the sound effects and vocal percussion while she belted the melody.
O Holy Night
In addition to pop music covers, Grimmie also performed various Christmas carols.
O Holy Night, she says in the video, is one of her favorites.
What Do You Mean?
Justin Bieber
Grimmie brought her unique spin to Justin Biebers hit 2015 song.
But Grimmies softer range lifts the melody to new emotional heights.
The video has since garnered close to 11 million views on YouTube.
Titanium David Guetta feat.
Sia
Grimmie covered another Sia song, this one from David Guetta.
