After confirming earlier this month a new album is coming, Tegan and Sara on Thursday released the first single, called "I'll Be Back Someday."

The track might sound familiar, because a portion of it was featured in the teaser for the record, titled Hey, I'm Just Like You, out Sept. 27 via Sire Records. As we previously mentioned, the album is made up of songs they originally wrote back in high school, some of the first music they ever created, tweaked and given new life for 2019.

"While working on our memoir, we discovered lost cassette tapes that had been unheard for over 20 years," says Tegan Quin of the upcoming record, the followup to 2016's Love You to Death. "They contained dozens of our first songs, written between the ages of 15 and 17 ... We immediately recognized the songs as an essential part of our high school story."

Sister Sara Quin has promised only "minor tweaks to lyrics and structure" were made to each of the tracks.
