Speedy Ortiz’s Sadie Dupuis has launched a new solo project under the name Sad13, and her first single is a collaboration with rapper Lizzo called “Basement Queens.” The song was produced by Computer Magic (Danielle Johnson, who was a band to watch over six years ago!), and created as part of a sponsorship with Google Docs. A behind-the-scenes video shows Dupuis and Lizzo collaborating on the song via a Google Hangout video chat and a Google Doc, followed by their in-person studio meetup to record the track. The song itself alternates between Lizzo’s rapping and Dupuis’ knotted guitar playing, and sounds like it digs deeper into the Destiny’s Child, TLC, and 3LW influences of Speedy Ortiz’s most recent album. You can listen to it and download it for free (in exchange for payment information) on the Google Play Store and watch the making-of video below.
