Clairo collaborator Sassy 009 announces mixtape with new single "Mystery Boy"

"Mystery Boy" is the third outing from Sassy 009's Heart Ego mixtape, following "Here Comes The Weekend" and "Blue Racecar".

Heart Ego will be Sassy 009's first project since 2019's KILL SASSY 009 EP. Lingård says of the mixtape, "Heart Ego is the most ambitious project I’ve done so far in my career, yet the project I have had the most trouble defining. Framing it as a mixtape was like finding home. The actual structuring and understanding of my compositions is simply a result of how I think it should feel, and not necessarily in line with a structure someone else completely understands."

Tracklist:

1. Forever Seventeen
2. Blue Racecar
3. Mystery Boy
4. Here Comes The Weekend
5. Red Plum
6. Wannabe
7. It’s Complicated
8. Ego Heart Ego
