Tobias Jesso Jr. has shared a super-smooth new demo titled "Don't"

His lauded debut record Goon arrived last year, and following its success he found himself writing with and for Adele and Sia.

"Don't" is a pared-back oeuvre that sees Jesso marry his yearning vox with jazzy keys. It's unknown what the demo is for, or whether it's just something he needed to lob out into the wild, but it's gonna break hearts just as it is.
