Glass Heart is Mel Parsons' fourth album, released on 30 November 2018 on Cape Road Recordings.

Many of the songs were written in North America, in Ohio, the Midwest, California, and on Prince Edward Island in Canada.

[10] Glass Heart is the first album Parsons recorded outside of New Zealand, in Santa Monica, California, USA.

After hearing Drylands, Froom agreed to work with Parsons, and they had a trial run in the studio in 2017 to determine if they were compatible, which they decided they were.

Even though Parsons had a backing band back in New Zealand, but it was impractical to bring them to the US for the recording sessions, so Froom assembled the band from local musicians, Kaveh Rastegar who plays bass for John Legend and Sia, Adam Levy who plays guitar for Norah Jones, and Ted Poor who plays drums for Andrew Bird.
