This is a single from, the full-length debut by Los Angeles-based female quartet Warpaint. The song originally began life as a cover of Nirvana's " Polly ," but mutated into their own song with the only similarity being that the words "hurt yourself" appear in both tunes.Bassist Jenny Lee Lindberg told BBC 6music: "[Guitarist] Theresa [Wayman] and I were just working and I had a bassline. She just started singing the lyrics to 'Polly' over that song. But instead of making that a cover - even though it sounded really cool - we said: 'Well, write your own words to the song.'"She continued: "There's definitely an homage to ['Polly'] in the chorus, the first line - [but] you listen to the songs back-to-back they sound nothing alike. Yeah, it is a bit of an homage to Kurt [Cobain] and Nirvana."
