In a new clip from the upcoming Kurt Cobain: Montage of Heck documentary, Kurt Cobain is singing a song from the grunge era. However, it's not one of his own Nirvana tunes.

In a clip posted online from the HBO documentary, Cobain is featured in a towel (along with Courtney Love, also in a towel), doing his best Chris Cornell impression by singing Soundgarden's 1991 track "Outshined" into a razor. The clip is short, but definitely gives fans some insight into Cobain and Love's personal life.

In a clip previously teased from the documentary, fans were treated to Cobain's cover of Paul McCartney's A Hard Day's Night ballad "And I Love Her." Kurt Cobain: Montage of Heck premieres May 4 on HBO.
