Bikini Kill announced last month that it would debut three unreleased tracks on a reisue of Revolution Girl Style Now!, and Rolling Stone premiered one of the “new” songs, “Playground,” on Tuesday.

Dark and grungey, it was recorded when the band first laid down Revolution, which was self-released in 1991. Per a release, the tape actually ran out just as the band finished “Playground.” The other two unreleased songs, “Ocean Song” and “Just Once,” were also recorded at the same time.

Frontwoman Kathleen Hanna told Rolling Stone, “For some reason we didn’t mix them. I’m pretty sure there wasn’t enough room on the cassette tape.”

The Revolution Style Girl Now! reissue is due out Sept. 22 via Bikini Kill Records. For more, head to Rolling Stone.
