Karen O - 'Duet' [live on Triple J]

It's been a while since we've heard anything from the Yeah Yeah Yeahs, but frontwoman Karen O has played a new song on Australian radio.

Karen O’s 'Psycho-Opera' Stop the Virgens hit Sydney Opera House on Sunday night, and she teamed up with guitarist Jason Grisell on radio station Triple J to offer a preview of the show’s soundtrack.

For Stop the Virgens, Karen O worked with The Creators Project and director and Pulitzer Prize finalist Adam Rapp.

You can listen to the song, called 'Duet', and the interview where Karen tries to explain what exactly a psycho-opera is, below.
