Kara Jane Spencer, from Derbyshire, had a severe form of ME, which left her unable to walk, and she died in January 2023, aged 32.
But before her death, a team of more than 100 musicians and producers helped record and release an album, It's Still ME, in 2020.
A second collection of the Shirebrook resident's work is being released on Friday to celebrate her legacy and promote Severe ME Day.
