This album, the first under the band's name in six and a half years, is a jazz alternative album with a multilingual and hardcore taste that differs greatly from previous albums.
Recorded sporadically over five years from 2015 to 2019, Sixty Summers was shaped profoundly by Stone’s key collaborators on the album: Thomas Bartlett, aka Doveman, and Annie Clark, the Grammy-winning singer, songwriter and producer known as St. Vincent. Bartlett and Clark were the symbiotic pair Stone needed to realise her first pop vision. A wizard of production and songwriting, Bartlett helped coax Sixty Summers’ independent, elemental spirit from Stone, writing and recording over 50 demos with her at his studio in New York.
