The British singer revealed a tender, piano-led cover of Cyndi Lauper's 1986 hit "True Colors." Stripped of any percussion and beat, the song begins with just the singer and her piano, before growing into a gorgeous blend of bells, synths, guitar strums and Marina's reverb-heavy vocals.
Spin says the cover was supposedly intended for a potential reissue of Froot (that Marina had spoken about during the summer) but never came to fruition. Still, consider this "True Colors" cover a must-add on our list of unreleased Marina & The Diamonds gems.
