A ways back, we heard that St. Vincent would be joining Grimes this year on the Girls soundtrack. Her contribution, “Teenage Talk,” finally premiered during the most recent episode.

The song was recorded in 2014 but didn’t make it on to St. Vincent’s self-titled album. The snippet ripped and posted to tumblr has a dreamy, singsong vibe that could have fit on any of Annie Clark’s album, but has a sad sweetness to it that separates “Teenage Talk” from the grittier distortion of last year’s release.

Stream the demo below, and look out for Grimes’ contribution in this season’s remaining episodes.
