They teased a collaboration back in January when Macklemore posted a picture of the pair on his Instagram.
In a recent interview with Rolling Stone, Macklemore described his time working with Kesha: “She’s a musician, she’s a writer, she’s someone that is not afraid to try ideas in the studio, not afraid to get vulnerable in front of people, not scared to go for the high note when she doesn’t know if she can hit it or not.
“She is a musician in every sense of the word, and she’s hilarious.”
‘Good Old Days’ will be on Macklemore’s album ‘Gemini’, which comes out on Friday (September 22).
Macklemore previously released ‘Marmalade‘, a track with Lil Yachty. The video featured the pair played by child versions of themselves.
Kesha’s album ‘Rainbow‘ was released in August.
