Heart-Shaped Box is the first release in Mark’s COVERED-19 series, where she put out covers and originals created in self-isolation during the coronavirus lockdown in NYC.

Mark stated that she was keen to remain productive during the ongoing global pandemic and resulting self-isolation, saying:

For me making music in the covid-19 quarantine has probably been the only positive to come out of a tragedy like this. All the pressure I normally feel when working on music is lifted. That’s the beauty in the music I’m making right now: it’s just me whipping up whatever I’m feeling. Keeping it minimal has been the key mentality for me and just having fun with it. I used to stress so much about visuals and the message I was sending with my music. I’ve learned a lot about myself already during the quarantine, and hope to keep this mentality going when all of this is finally over.
